How to Understand Audacity’s Menus

File menu – File. The File menu has commands to create, open, and save Audacity projects, import and export audio files, and perform batch actions using the Chains command.

• New – New ( Ctrl+N ). Create a new and empty project window to start working with new or imported channels. This new workspace can then be saved as an Audacity project file ( .AUP ) for easy and complete access to its contents via the Save Project or Save Project As commands. … (Save Project As…) of the File menu.
• Open… – Open… ( Ctrl+O ). Opens a file selection window where you can: (1) Open one or more Audacity project files ( .aup ) or (2) Import one or more audio files or a list of files ( .LOF ).
  • You can also use File > Import > Audio… – File > Import > Audio… to import audio files into the project.
  • Import implies bringing new content into the Audacity project in any way, such as via the File > Open, File > Import command or dragging files into the project window. That content is usually an audio file such as a WAV or MP3 , but (using File > Import ) can also be an elegant channel, a MIDI file, or raw data (Raw Data).
  • For audio files, the importer used depends on the file type in File > Open or File > Import > Audio… and the Extended Import Preferences settings (when the Edit > Preferences > Extended Import command is selected).
• Recent Files .
  • Lists the full path to the 12 last saved or opened projects or most recently imported audio files. The oldest entries at the bottom are discarded as new ones are added at the top. When you delete an Audacity project or audio file, it will remain in the list, but will be removed from the list if you select it.
  • To clear the entire list, select “ Clear ” just below the last item of the list.
• Close – Close ( Ctrl + W ). Closes the active project window, prompting you to save your work if you haven’t already.
• Save Project – Save the Project ( Ctrl + S ).
  • Save the current audacity project in its original, uncompressed quality using the AU repository format. An AUP project file is created, along with a folder with the same name as the AUP file containing the project’s audio data. For example, if you save the project as chanson.aup , a folder named chanson_data will contain that audio data.
  • Audacity projects are not intended to be read by other applications, but to upload and save audio in Audacity, with all project data such as label channels. When you are finished working on the project and you want to use the results in another application, choose one of the Export commands.
• Save Project As… (Save as new project). Same as “ Save Project ” above, but allows you to save a copy of the project with a different name or location. This can be useful if you want to preserve the status quo of the project at a certain point in time, and then proceed with the project you just saved.
• Export (Export). The Export submenu allows you to export audio from Audacity in audio file formats that can be read and played by other applications. You can also export label files or MIDI files, or save a compressed copy of your project as a set of files in the Ogg Vorbis format.
• Import (Import). The Import submenu allows you to import audio files or label files into your project. Files in different audio formats can be imported into Audacity.
• Chains .
  • Chain is an automated sequence of commands similar to a “macro”. It is often used to batch process a group of audio files, or to automate the application of a set of effects to a project, with identical sequence of effects/functions.
  • The Chains submenu has two commands for working with the chain of command, one for creating and editing ( Edit ) the chain of commands, and the other for applying ( Apply ) the chain.
• Page Setup… (Page Setup). Mine the standard Page Setup dialog box before printing.
• Print… (Printing…).
  • Prints all waveforms in the active project window (and the contents of the label or other channels), with the timeline above. Everything is printed on one page.
  • To include the Track Contrp Panel , or to print other parts of the interface, you can use Screenshot Tops (screen capture tools) to capture the screen to print to a file, then use print function of your favorite photo editor.
• Exit – Exit ( Ctrl + Q ). Close all project windows and exit Audacity. If there are any unsaved changes to your project, Audacity will ask if you want to save them. Note that it is not necessary to save the changes if you have already exported your blend as a WAV or MP3 file and you are happy with it. But if you’re working with a blend and plan to continue working with what you already have, saving an audacity project will allow you to restore everything, just as you saved it.

Menu Edit – Edit. The Edit menu has standard commands such as Undo , Redo , Cut , Copy , Paste , Delete , plus many more specialized commands for editing sounds. bar or label.

• Undo – Defer ( Ctrl + Z ). Postpone the last editing action you took on your project. You can postpone as many times as you want, until you have just opened that window. To defer multiple actions, choose the View > History… command (View > Done…). The name of this menu item will change to reflect what will be deferred; If you’ve just recorded some sound, the name of that menu item will be Undo Record .
• Redo – Redo ( Ctrl + Y ). Redo any editing animations that have just been postponed. After you perform a new editing operation, you may no longer be able to redo actions that were deferred.
• Cut – Cut ( Ctrl + X ). Remove the selected audio data and/or labels and place them in the Audacity cache. The sound or labels after that selection will shift to the left hand side.
• Delete – Delete ( Ctrl + K ). Similar to the Cut command, but removes the currently selected audio data and/or labels without copying them to Audacity’s cache.
• Copy – Copy ( Ctrl + C ). Copy selected audio data to Audacity’s cache without removing it from the project.
• Paste – Paste ( Ctrl + V ). Paste the previously cut or copied audio into Audacity’s buffer, or insert it into the selected channel(s) where the cursor is located, or replace the currently selected region(s).
• Duplicate – Duplicate ( Ctrl + D ). Creates a new channel with only the selected part as a new file.
• Remove Special – Remove Special. Remove Special has the following submenus:
  • Split Cut and Split Delete are “special” cut or delete commands that make the audio or labels to the right of the selected part stay in place instead of shifting to the left.
  • Silence Audio mutes the selected part.
  • Trim Audio removes all audio from the active file except the selected part, creating its own file separate from the rest of the selected audio.
• Clip Boundaries . The Clip Boundaries submenu has commands for creating or removing separate files in an audio channel. A file within an audio channel is a split of that channel that has been split so that it can be controlled relatively independently of other files in that channel.
• Labels – Labels. The Labels submenu has commands that allow you to add and edit labels.
  • This command invokes the label editor to allow you to add or remove label channels and edit their labels entirely using the keyboard, so is especially useful for visually impaired users.
  • It opens a dialog showing all the tabular labels accessible from the keyboard. A pinch of knobs in the dialog box let you insert or delete labels, or import and export labels to a file.
• Labeled Audio – Label Audio. The Labeled Audio submenu has commands that offer a time-saving way of performing Edit menu actions on fully selected multi-label audio.
  • The commands apply to all labeled audio regions that are completely inside the selected part in a label channel. The selected part can extend beyond those label borders, but unlabeled audio and audio whose region label is only part of that selection will not be affected.
  • If no audio channels are in the selected section, then the Labeled Audio commands will apply to all audio channels in the project. However, if you only select certain audio channels, then the Labeled Audio commands will affect only those selected audio channels.
• Metadata… – Metadata… Use this function to edit the metadata tags that will be applied to the exported files.
• Preferences… ( Ctrl + P ). Displays the Preferences dialog box. Preferences allow you to change most of Audacity’s default settings and behaviors.

Select menu. The Select menu has commands for specifying selections (before working with them with edit commands, effects, and exports) or the position of the edit cursor. You can also choose between and navigate audio files.

• All – All ( Ctrl + A ). Select all sounds in all channels.
• None – Nothing ( Ctrl + Shift + A ). Deselect all audio in all channels.
• Tracks – Tone range. The Tracks submenu has commands to extend the current selection up and/or down in all channels, or in all Sync-Locked channels in the project.
• Region . The Region submenu has commands to define selections and allows you to store and retrieve the position of the editing cursor or selection.
• Spectral . The Spectral submenu has commands that allow you to make spectrum selections (Spectral) that can be used to make selections of frequency ranges as well as durations in the Spectogram view. Spectrum selection is used with special editing effects to change the frequency content of the selected audio.
• Clip Boundaries . The Clip Boundaries submenu (file borders) allows you to choose between the editing cursor and file borders, or navigate through files, selecting all for the current file.
• Cursor to Stored Cursor Position – Points to the store cursor position.
  • When playing or recording (or pausing): selection is made from the position of the playback cursor

    to the previously saved position with the Select > Store Cursor Position command. To make it easier to use without pausing, you may want to add a keyboard shortcut for ” Cursor to Stored Cursor Position “.

  • When there is no active sound: select from the current position of the editing cursor (or from the left edge of the current selection) to the stored position.
  • The alternative procedure if you want to store multiple locations then add a label when required at the edit cursor or the playback/recording cursor.
• Store Cursor Position . Save the cursor position as defined below, which can then be used with the Select > Cursor to Stored Cursor Position command to create or modify a selection.
  • If audio is not actively playing, recording or paused: the stored cursor position is the position of the editing cursor or the left edge of the selection.
  • If the sound is positive: the stored cursor position is the position of the replay pointer

    at the time you execute the archive command. To make it easier to use without pausing, you may want to add a keyboard shortcut for ” Store Cursor Position “.

  • If you want to save the position of the editing cursor (or even the borders of the selection) while the audio is active, use the Select > Region > Store Selection command.
• At Zero Crossings ( Z ). Helps avoid pressing on edit points when performing clipping and joining by moving the selection edges (or cursor position) very gently so that they are at the zero point of intersection.

Menu View – View. The View menu has commands that determine how much detail you see in all channels in the project window. It also allows you to show or hide toolbars and some windows like Undo History .

• Zoom . The Zoom submenu has commands that allow you to control the amount of sound, for longer or shorter periods of time, visible on the screen.
• Track Size . The Track Size submenu has commands that help you make your project fit the screen horizontally and vertically.
• Skip To . The Skip To submenu has commands that allow you to actually skip the cursor position to the beginning or end of your current selection.
• History… – Did…
  • Opens a History window that can then be left open when using Audacity. History lists all actions that were not uploaded but performed in the current project, including imports. The right-hand column shows the amount of hard disk space each action used, and the total amount of space used is shown in the first (uneditable) box below that list. In the project shown in the figure below we have standardized both the recorded channel and the Risset Drum drum channel, so Normalize takes up a little more space than the recording takes up.
    

    {“smallUrl”:”https://www.wikihow.com/images_vi/9/9c/History_Dialog.png”,”bigUrl”:”/images/thumb/9/9c/History_Dialog.png/387px-History_Dialog.png “,”smallWidth”:460,”smallHeight”:453,”bigWidth”:387,”bigHeight”:381,”licensing”:”<div class=”mw-parser-output”><p><a href= “/index.php?title=B%E1%BA%A3n_m%E1%BA%ABu:Screenshot&redlink=1″ class=”new” title=”Bu1ea3n_mu1eabu:Screenshot (page chu01b0a u0111u01b0u1ee3c viu1ebft)”>Bu1ea3n_mu1eabu:Screenshot</b> a>n</p></div>”}
  • If you remove the Undo levels, you can reclaim the disk space used by the project. To save most disk space (remove the ability to postpone or redo any past edits), select Action at the bottom of the list using the mouse or the arrow keys Up or Down of the keyboard, increase “ Levels to Discard ” to the largest number possible and then click “ Discard ”.
  • You can also easily jump backward or forward between editing steps by selecting entries in the window. This can be faster than selecting the Undo and Redo commands multiple times from the Edit menu.
• Karaoke… Karaoke displays the ball that follows the text while playing the sound. Karaoke command… catalyzes whenever you have at least 1 label channel. If you have multiple label channels, it only uses the first label channel.
• Mixer Boards… . The Mixer Board… is an alternative view of the audio channels in the main channels window, and is analogous to the hardware mixer controller. Each audio channel is displayed in a Track Strip . Each Track Strip has its own pair of gauges, a gain slider, a stereo balance slider ( pan slider ), and mute/spo (mute/play alone) knobs, and echoes. channel control in its Track Contrp Panel . The Mixer Board… command is activated whenever an audio channel is available – it can even be used during playback.
• Extra Menus (on/off) . Displays extensive menus with many commonly used commands. They appear behind the Help menu.
• Show Clipping (on/off) .
  

  

  {“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/82/Showclipping02.png/460px-Showclipping02.png”,”bigUrl”:”/images/thumb/8/82/Showclipping02 .png/515px-Showclipping02.png”,”smallWidth”:460,”smallHeight”:94,”bigWidth”:515,”bigHeight”:105,”licensing”:”<div class=”mw-parser-output” ><p><a href=”/index.php?title=B%E1%BA%A3n_m%E1%BA%ABu:Screenshot&redlink=1″ class=”new” title=”Bu1ea3n_mu1eabu:Screenshot (page chu01b0a u0111u01b0u1ee3c viu1ebft) )”>Bu1ea3n_mu1eabu:Screenshot</a>n</p></div>”}
  • If enabled (off by default), individual or multiple clipped samples display as a red vertical line when in one of the waveform views. A sample is displayed as clipped if it touches or exceeds 0 dB and therefore moves to or exceeds the volume envelope defined between +1.0 and -1.0 in the vertical to the left of the waveform. .
  • A sequence of 4 or more consecutively clipped samples will also enable the red clipping indicator on the Meter Topbar (Measurement Toolbar). A solid red block in the waveform almost certainly indicates multiple sequences or extended sequences where the audio information beyond 0 dB is lost, causing severe distortion. Avoid clipped samples wherever possible, for example by setting the correct recording level. You can turn off “ Show Clipping ” if it behaves sluggishly on slower machines.

Transport menu. The Transport menu commands allow you to play or stop, repeat, play, or record (including timed or sound-activated recording). Except for Scrub Play , those replays play at standard speed, or are sped up or down over time by adding the Time Track envelope. The easiest way to play at a fixed faster or slower speed is to use the Transcription toolbar.

• Play – Play. The Play submenu commands control replay in Audacity. You can Start , Stop , or Pause to play back the audio in your project.
• Record – Record sound. The Record submenu commands control recording in Audacity. You can Start , Stop , or Pause to play back the audio in your project. You can also start recording in an existing channel or on your new channel.
• Scrubbing – Scrubbing. Opens a submenu where you can start, stop or switch to Scrub or Seek play, or enable/disable Scrub Ruler .
• Cursor to – Point to. The Cursor to submenu commands allow you to move the cursor to the beginning or end of a selection, channel, or any adjacent audio files you may have.
• Play Region – Play Region. The Play Region submenu commands allow you to lock and unlock the play zone.
• Rescan Audio Devices – Rescan audio devices. Rescan audio devices connected to your computer, and update the drag and drop playback and recording menus in the Device Topbar .
• Transport Options – Transport options. The Transport Options submenu allows you to manage and set up different options for moving (playing and recording) in Audacity.

Tracks menu – Tone range (or audio channel). The Tracks menu has two commands: (1) To create and remove channels; and (2) To apply operations to selected channels such as mixing , resampling , stereo to mono conversion, adjustment or mute.

• Add New (Add New). The Add New submenu has commands for adding stereo or mono channels, label channels, and timing channels.
• Mix – Mix. The Mix submenu has commands for mixing and returning for your selected channels a single stereo or mono channel.
• Resample… – Resample… Allows you to resample the selected channel(s) with a new sample frequency for use in the project, leaving the length (and hence the replay rate and pitch) ) constant. To resample for export, change the Project Rate on the selection toolbar ( Selection Topbar ).
• Remove Tracks – Removes the channel.
  • Remove the selected channel(s) from the project. Even if only part of a channel is selected, the entire channel will be removed. You can also remove a channel by clicking the X in the top left corner.
  • To remove only the selected audio in a channel (without bringing it to the clipboard), use the Edit > Delete or Edit > Remove Special > Split Delete or Edit > Remove Special > Silence Audio command.
• Mute/Unmute – Mute/Unmute. The Mute/Unmute submenu allows you to mute or unmute all the channels in your project at once, without having to use the Mute and Unmute knobs in the Track Contrp Panel of each channel. .
• Pan – Stereo balance. The Pan submenu allows you to change the stereo balance of all the channels you selected or select a part, at once, without having to use the stereo balance sliders ( Pan Sliders ) in the Track Contrp Panel (Panel). Channel control) of each channel. Stereo equalization choices are extreme left ( Left ) or right ( Right ) or center ( Center ). If no channel is selected, the balance is/is altered in all channels.
• Align Tracks – Adjust channels. The Align Tracks submenu has commands that help you adjust the selected channels in different ways. In particular, there are two very useful commands that allow you to tune channels from start to finish, channel to channel, or tune them all together.
• Sort Tracks – Sort channels. The Sort Tracks submenu has commands to sort channels by Track Names or when they started.
• Sync-Lock Tracks (on/off) – Sync – Channel Lock (on/off). The Sync-Lock feature ensures that length changes that occur anywhere in a defined group of channels will also occur in all audio channels or labels in that group, even if those channels was not selected. This allows you to keep existing sounds or labels in sync with each other, even when performing actions like inserting, deleting, or changing speed or tempo. You can turn this feature on (on) or off (off by default) by clicking on that menu item.

Generate menu – Generate tones. The Generate menu allows you to create sounds with tones, noises, or silences. The generated sound can be inserted at the cursor position to expand the channel, or the existing selection can be replaced with a newly created sound. Although by default, no keyboard shortcuts are provided for the generators, it is possible to create your own shortcut for any Generate command. See Keyboard Preferences for help creating keyboard shortcuts.

• Audacity’s Generators – Audacity’s generators.
  • The available sound generators are: Chirp , DTMF , Noise , Silence and Tone .
  • The built-in sound generators that come with Audacity are: Rhythm Track , Pluck , Risset Drum and Sample Data Import . Other plug-ins can be added in different formats.
• Add / Remove Plug-ins… – Add/Remove Plug-ins. Selecting this option from the Generate menu (or the Effect menu or the Analyze menu) brings you to a dialog box that allows you to load and unload sound generators (and effects – Effects and analyzers) . ) from Audacity. This allows you to customize the Generate menu making it shorter or longer as required. See Plug-in Manager: Effects, Generators and Analyzers for more details.
• Use Audacity’s sound generators.
  • Create a sound in a new channel: If no channel exists, select the required sound generator. If there are existing channels, click outside of them (gray background) to deselect them, then select Generate .
  • Insert the generated sound at the cursor position: Place the cursor on the channel and select Generate . The specified audio length will be inserted into the selected channel(s) at the cursor position. The total length of the selected channel(s) will therefore increase.
  • Replace existing selection with generated sound: Select region then Generate . The selected area(s) will be/replaced with the generated sound. The total length of the selected channel(s) will remain the same, unless you change the length in the tone generator to replace the selected part with a longer or shorter length.
  • Amplitude – Amplitude. All built-in sound generators (except Silence , of course) allow you to type the amplitude value of the loudness of the generated sound. Allowed values are between 0 (silent) and 1 (maximum possible volume without clipping), with a default of 0.8.
  • Duration – Length. Type (or use your keyboard’s arrow keys) to enter the required range. If the first digit you want is displayed, type in the entire number. If the first number requested does not appear, use the Left or Right arrow key on the keyboard to shift the first number, and then type. You can also increase the number shown with the Up or Down arrow keys instead of typing.
  • Selection Format for Duration – Selection format for the time period. Whether the creation is selected or not, you can change the Selection Format to another Duration unit so that the creation will fall within those units. To do this, open the contextual menu by tapping the triangle to the right of the numbers. You can also open that menu by hovering over or selecting among the Duration numbers, then right-clicking or using the equivalent key on your keyboard.
• Built-in Generators – Built-in Generators
  • Chirp… Chirp generates 4 different tones similar to the Tone Generator but allows additional setting of amplitude and frequency at the beginning and end. Short tones can be made to sound very much like a bird song. For Tone , frequencies can be nominally anywhere between 1 Hz and half the current project frequency as indicated in the selection toolbar ( Selection Topbar ).
  • DTMF Tones… Generates dual-tone multi-frequency tones – DTMF ( Dual-Tone Multi-Frequency ) like the tones produced by knobs on telephones. For each tone you want to create, type in the numbers 0 through 9, lowercase letters a through z, and the characters * and #. You can also type in the 4 “priority” tones used by the US Army (capital letters A, B, C, and D).
  • Noise… – Noise. Generates 1 of 3 different types of noise. White noise has the greatest ability to mask other sounds, as it has similar energy at all frequency levels. Pink noise and Brownian noise both have more energy at lower frequencies, especially Brownian , it has the most muffled bass of the three. By their very nature, violet and Browni noise can have few inaccuracies at the required amplitude if the channels are only a few seconds long.
  • Silence… – Silence. Produces zero amplitude (0) sound, configurable setting unique to duration. When applied to an audio selection, the result is the same as the Edit > Remove Special > Silence Audio command.
  • Tone… – Tone. Spawns 1 of 4 different tonal waveforms: Sine , Aquare , Sawtaooth and Square (no nickname). The name of each tone carefully describes its appearance when zoomed in enough to see each waveform period.
• Plug-in Generators – Pre-built sound generators. Any additional sound generators that appear below the menu separator are Nyquist , LADSPA or LV2 plug-ins. Click the links in the previous sentence to see how to add new plug-ins of each type. Audacity includes the following Nyquist sound generators, but more are available to download as Nyquist plug-ins on our Wiki.
  • Pluck… . Synthetic jerky tone with abrupt or step-by-step output fades, and the selected pitch corresponds to the MIDI tone.
  • Rhythm Track… – Rhythm channel. Creates a channel with regular sounds at the specified speed and beat counts for each beat (measure bars). It can be used as a metronome to establish a steady beat upon which further recording can be performed.
  • Riset Drum… Generates a real drum sound consisting of a sine wave modulated by narrowband noise, a close tonal interval, and a fairly strong sine wave at the base.
  • Sample Data Import… – Import sample data. Generate tones from imported numeric data.

Menu Effect – Effects. Audacity has many built-in effects and also allows you to use a wide range of preset effects. You can download many free plug-ins for Audacity from our website. Plug-ins always appear below the divider in the Effect menu. This version of Audacity has Nyquist and/or LADSPA sample effects.

• Use effects. Headers ending with 3 dots (…) will bring up a dialog box asking you to add parameters. All effects have a dialog box that allows you to hear the sound as modified by the effect before you apply the effect to the waveform.
  • The built-in effects and Nyquist plug-ins have a Preview knob – click it to hear if the current effect settings are what you want, and if not, change those settings and then Preview again. Click OK to apply that effect to the waveform.
  • All other effect types supported in Audacity ( LADSPA , LV2 , VST and Audio Units for Mac ) support real-time preview – you can change effect settings while listening and then press Apply . application) to apply the effect to the waveform.
• Add / Remove Plug-ins… – Add / Remove plug-ins. Selecting this option from the Effect > Add/Remove Plug-ins… menu (either the Generate menu or the Analyze menu) brings you to a dialog box that allows you to load and unload effects (and sound generators and components). analyzer) from Audacity. This allows you to customize your Effect menu making it shorter or longer as required. For more see Add/Remove Effects , Generators and Analyzers . By default all built-in effects, with the exception of Classic Filters, are loaded into Audacity.
• Repeat Last Effect – Repeat the Last Effect ( Ctrl +R ). Using this command from the Effect menu will repeat the last effect you used with the same settings. For quick access to the last effect used, you can use Ctrl+R to repeat it with the same settings.
• Audacity’s built-in effects.
  • Audacity’s built-in effects (effects that appear in the application regardless of Audacity’s assets folders and other ” Plug-Ins “) are above the divider in the browser Single Effect .
  • The built-in effects support saving user presets but not yet support real-time preview or import/export presets from/to other machines.
• Nyquist effects.
  • The Nyquist plug-ins offer most of the effects below the divider in the Effect menu. They are also used to provide some generators and analyzer tools. A wide range of Nyquist effects, sound generation and analysis plug-ins can be obtained from Download Nyquist Plug-ins on our Wiki.
  • Nyquist effects support saving user presets but not yet support real-time preview or import/export presets from/to other machines.
• LADSPA effects.
  • LADSPA ( Linux Audio Developer’s Simple Plug-in API ) plug-ins were originally developed for the Linux platform, but some plug-ins are also written for Windows and Mac. Most LADSPA plug-ins are effects, but they are also used to provide some of the built-in sound generators in Audacity and can be used for audio analysis.
  • Additional LADSPA plug-ins can be downloaded for Linux, Mac, and Windows. See the LADSPA section of the Download page on the Audacity website for more details.
  • LADSPA effects support real-time preview. They do not support importing/exporting presets but do support saving presets for use in Audacity only. Some LADSPA plug-ins have an “ Effect Output ” section present after the effect is applied.
• LV2 effects . LV2 is a more advanced evolution of the LADSPA plug-in architecture. Note that the LV2 effects in Audacity cannot yet display the full graphical interface.
• VST effects. Virtual Studio Technology – VST ( Virtual Studio Technpogy ) is a software interface that integrates audio synthesizer software and effects plug-ins with audio editors and recording systems, like Audacity.

Analyze menu – Analyze. The Analyze menu has tools to figure out the characteristics of your sound, or label key features. Plug-ins that accept audio input but produce no audio output will be placed in the Analyze menu, with analysis results being provided by labels (or in some optional LADSPA plug-ins by the “ Effect Output ” section of the plug-in itself). Although no keyboard shortcuts are provided by default for most analysis tools, it is possible to set up your own keyboard shortcuts for any of the Analyze commands. See Keyboard Preferences for instructions.

• Audacity’s analysis tools.
  • There are 3 built-in LADSPA analysis tools: Contrast , Plot Spectrum and Find Clipping .
  • There are five analysis tools that are Nyquist plug-ins that come with Audacity: Beat Finder , Regular Interval Labels , Sample Data Export , Silence Finder and Sound Finder .
  • Vamp Analysis Plug-in
• Add / Remove Plug-ins… – Add/Remove Plug-ins. Selecting this option from the Analyze menu (or Effect menu or Generate menu) brings you to a dialog box that allows you to load and unload Analyzers (and Effects and Generators) . ) from Audacity. This allows you to customize your Analyze menu to make it shorter or longer as required. See Plug-in Manager: Effects, Generators and Analyzers for more details.
• Built-in LADSPA analysis tools.
  • Contrast… – Contrast ( Ctrl + Shift + T ). Single, selected non-stereo audio channel analysis to determine the average rms difference in volume (contrast) between the main background (talk) and the secondary background (music, auditorium noise or similar). The goal is to determine whether the talk will be understandable to people with hearing impairments.
  • Plot Spectrum… Takes selected sound (set of sound pressure values at times) and converts it to a graph of frequency (horizontal in Hz) and with amplitude (vertical in dB) .
  • Find Clipping… – Find clipping. Show clipped samples in a label channel, as the reader’s screen-accessible alternative to the View > Show Clipping command. The section must have at least 1 truncated pattern, but may include samples that are not truncated.
• The analysis tools are the Nyquist plug-in that comes with Audacity. To add a new Nyquist plug-in, place it in the “ Plug-Ins ” folder of Audacity.
  • On Linux, the “ plug-ins ” folder is in usr/share/audacity in bold if you installed the Audacity package from your distribution, or in usr/local/share/audacity if you compiled Audacity from source. The “ plug-ins ” folder can also be created in the home root directory, located at: ~/.audacity-files/plug-ins (you can also call that folder ” plugins “).
  • On Mac, the “ Plug-Ins ” folder is in ~/Library/Application Support/audacity/Plug-Ins .
  • On Windows, the ” Plug-Ins ” folder is in the folder where Audacity is located – usually C:Program Files on 32-bit Windows or C:Program Files (x86) with 64-bit Windows.
• Beat Finder… . Try to put the labels on beats much louder than the ambient sound. This is a pretty rough and ready tool, and won’t necessarily work well on a modern pop channel with compressed dynamic range.
  • Regular Interval Labels… – Regular Interval Labels… Put the labels in a long channel to divide it into smaller segments of equal size. For example, this can be useful for distributing a large file over the Internet. You can either choose the number of labels to be generated, or the interval between them. Each generated label has the label text selected.
  • Sample Data Export… – Export Sample Data… Reads next sample values from selected audio and prints this data to raw text, CSV or HTML file.
  • Silence Finder… – Silence Finder. Split channels by placing point labels inside silent regions. Use this if you only want to split the recording into tracks at certain points without removing the silence between them.
  • Sound Finder… – Sound Finder. Split channels by setting zone labels for audio regions separated by silence. Use this to generate labels that indicate the exact region of each channel to be mined. This allows you to remove some or all of the silence between channels.
  • Vamp Analysis Plug-ins – Vamp Analysis Plug-ins. You can also add some extra analysis tools in the Vamp plug-in format to view and analyze the descriptive content of music files. Usually the things the Vamp plug-in can take into account include the location of moments such as time and power, or the fundamental frequency data to start noting. Plug-ins that create graphs or other images will not work in Audacity, other than just those that are suitable for writing labels.
