Commands and Keyboard Shortcut Reference

From Audacity Development Manual
Jump to: navigation, search


This page lists all commands in the menus and all keyboard shortcuts. The default Standard set of shortcuts is a reduced set, compared to earlier versions of Audacity, to simplify the set of shortcust somewhat and to provide greater flexibilty for users who wish to create their own shortcuts. There is also an extended Full set of keyboard shortcuts that can be selected from the Defaults button on the Keyboard Preferences dialog. This Full set is the set that was available in Audacity 2.1.3 and earlier. You can use Keyboard Preferences to change or remove existing shortcuts or to assign a shortcut to commands that lack a default shortcut.
  • Standard shortcuts are shown like so: Ctrl + A.
  • Shortcuts that are only in the Full set are shown like so: Ctrl + #   Extra.
  • Shortcuts that have not been assigned, that you can assign using keyboard preferences, are shown like so (unassigned).

Some less commonly used commands are not in the default menus but they can be accessed by menu by enabling Show extra menus in Interface Preferences.

Bulb icon For menu commands that are enabled (not grayed-out) if you Shift and click on the sub-menu item, instead of executing the command the Keyboard Preferences opens at the chosen command.

  • See Audacity Selection for examples of changing track focus and selection.
  • PAGE UP scrolls the project rightwards and PAGE DOWN scrolls the project leftwards, equivalent to a single click in the white area either side of the horizontal scrollbar. These shortcuts cannot be configured in Keyboard Preferences.
  • There are a number of key combinations that can be used in combination with mouse clicks. These cannot be configured. They are listed on Mouse Preferences

In All Tracks Ctrl + Shift + K Extends the current selection up and/or down into all tracks in the project.
In All Sync-Locked Tracks Ctrl + Shift + Y Extends the current selection up and/or down into all sync-locked tracks in the currently selected track group.

Select: Region

For modifying, saving and restoring a selection.
Action Shortcut Description
Left at Playback Position [ When Audacity is playing, recording or paused, sets the left boundary of a potential selection by moving the cursor to the current position of the green playback cursor (or red recording cursor).

Otherwise, opens the "Set Left Selection Boundary" dialog for adjusting the time position of the left-hand selection boundary. If there is no selection, moving the time digits backwards creates a selection ending at the former cursor position, and moving the time digits forwards provides a way to move the cursor forwards to an exact point.

Right at Playback Position ] When Audacity is playing, recording or paused, sets the right boundary of the selection, thus drawing the selection from the cursor position to the current position of the green playback cursor (or red recording cursor).

Otherwise, opens the "Set Right Selection Boundary" dialog for adjusting the time position of the right-hand selection boundary. If there is no selection, moving the time digits forwards creates a selection starting at the former cursor position, and moving the time digits backwards provides a way to move the cursor backwards to an exact point.

Track Start to Cursor Shift + J Selects a region in the selected track(s) from the start of the track to the cursor position.
Cursor to Track End Shift + K Selects a region in the selected track(s) from the cursor position to the end of the track.

Generate Menu

Generate
Action Shortcut Description
Add / Remove Plug-ins... (unassigned) Selecting this option from the Effect Menu (or the Generate Menu or Analyze Menu) takes you to a dialog where you can enable or disable particular Effects, Generators and Analyzers in Audacity. Even if you do not add any third-party plug-ins, you can use this to make the Effect menu shorter or longer as required. For details see Add / Remove Effects, Generators and Analyzers.

Effect Menu

Effect
Action Shortcut Description
Add / Remove Plug-ins... (unassigned) Selecting this option from the Effect Menu (or the Generate Menu or Analyze Menu) takes you to a dialog where you can enable or disable particular Effects, Generators and Analyzers in Audacity. Even if you do not add any third-party plug-ins, you can use this to make the Effect menu shorter or longer as required. For details see Add / Remove Effects, Generators and Analyzers.
Repeat Last Effect Ctrl + R Repeats the last used effect at its last used settings and without displaying any dialog.

Effect: Audacity

Effects built in to Audacity
Action Shortcut Description
Amplify... (unassigned) Increases or decreases the volume of the audio you have selected.
Auto Duck... (unassigned) Reduces (ducks) the volume of one or more tracks whenever the volume of a specified "control" track reaches a particular level. Typically used to make a music track softer whenever speech in a commentary track is heard.
Bass and Treble... (unassigned) Increases or decreases the lower frequencies and higher frequencies of your audio independently; behaves just like the bass and treble controls on a stereo system.
Change Pitch... (unassigned) Change the pitch of a selection without changing its tempo.
Change Speed... (unassigned) Change the speed of a selection, also changing its pitch.
Change Tempo... (unassigned) Change the tempo and length (duration) of a selection without changing its pitch.
Click Removal... (unassigned) Click Removal is designed to remove clicks on audio tracks and is especially suited to declicking recordings made from vinyl records.
Compressor... (unassigned) Compresses the dynamic range by two alternative methods. The default "RMS" method makes the louder parts softer, but leaves the quieter audio alone. The alternative "peaks" method makes the entire audio louder, but amplifies the louder parts less than the quieter parts. Make-up gain can be applied to either method, making the result as loud as possible without clipping, but not changing the dynamic range further.
Distortion... (unassigned) Use the Distortion effect to make the audio sound distorted. By distorting the waveform the frequency content is changed, which will often make the sound "crunchy" or "abrasive". Technically this effect is a waveshaper. The result of waveshaping is equivalent to applying non-linear amplification to the audio waveform. Preset shaping functions are provided, each of which produces a different type of distortion.
Echo... (unassigned) Repeats the selected audio again and again, normally softer each time and normally not blended into the original sound until some time after it starts. The delay time between each repeat is fixed, with no pause in between each repeat. For a more configurable echo effect with a variable delay time and pitch-changed echoes, see Delay.
Equalization... (unassigned) Adjusts the volume levels of particular frequencies.
Fade In (unassigned) Applies a linear fade-in to the selected audio - the rapidity of the fade-in depends entirely on the length of the selection it is applied to. For a more customizable logarithmic fade, use the Envelope Tool on the Tools Toolbar.
Fade Out (unassigned) Applies a linear fade-out to the selected audio - the rapidity of the fade-out depends entirely on the length of the selection it is applied to. For a more customizable logarithmic fade, use the Envelope Tool on the Tools Toolbar.
Invert (unassigned) This effect flips the audio samples upside-down. This normally does not affect the sound of the audio at all. It is occasionally useful for vocal removal.
Noise Reduction... (unassigned) This effect is ideal for reducing constant background noise such as fans, tape noise, or hums. It will not work very well for removing talking or music in the background. More details here.
Normalize... (unassigned) Use the Normalize effect to set the maximum amplitude of a track, equalize the amplitudes of the left and right channels of a stereo track and optionally remove any DC offset from the track.
Paulstretch... (unassigned) Use Paulstretch only for an extreme time-stretch or "stasis" effect, This may be useful for synthesizer pad sounds, identifying performance glitches or just creating interesting aural textures. Use Change Tempo or Sliding Time Scale rather than Paulstretch for tasks like slowing down a song to a "practice" tempo.
Phaser... (unassigned) The name "Phaser" comes from "Phase Shifter", because it works by combining phase-shifted signals with the original signal. The movement of the phase-shifted signals is controlled using a Low Frequency Oscillator (LFO).
Repair (unassigned) Fix one particular short click, pop or other glitch no more than 128 samples long.
Repeat... (unassigned) Repeats the selection the specified number of times.
Reverb... (unassigned) A configurable stereo reverberation effect with built-in and user-added presets. It can be used to add ambience (an impression of the space in which a sound occurs) to a mono sound. Also use it to increase reverberation in stereo audio that sounds too "dry" or "close".
Reverse (unassigned) Reverses the selected audio; after the effect the end of the audio will be heard first and the beginning last.
Sliding Time Scale/Pitch Shift... (unassigned) This effect allows you to make a continuous change to the tempo and/or pitch of a selection by choosing initial and/or final change values.
Truncate Silence... (unassigned) Automatically try to find and eliminate audible silences. Don't use with faded audio.
Wahwah... (unassigned) Rapid tone quality variations, like that guitar sound so popular in the 1970's.

Effect: LADSPA

"Linux Audio Plug-in Audio" effects
Action Shortcut Description
SC4... (unassigned) This effect is a stereo compressor with a variable envelope follower for RMS (average) / peak behavior.

Effect: Nyquist

Effects created using a LISP-variant called "Nyquist".
Action Shortcut Description
Adjustable Fade... (unassigned) enables you to control the shape of the fade (non-linear fading) to be applied by adjusting various parameters; allows partial (that is not from or to zero) fades up or down.
Clip Fix... (unassigned) Clip Fix attempts to reconstruct clipped regions by interpolating the lost signal.
Crossfade Clips (unassigned) Use Crossfade Clips to apply a simple crossfade to a selected pair of clips in a single audio track.
Crossfade Tracks... (unassigned) Use Crossfade Tracks to make a smooth transition between two overlapping tracks one above the other. Place the track to be faded out above the track to be faded in then select the overlapping region in both tracks and apply the effect.
Delay... (unassigned) A configurable delay effect with variable delay time and pitch shifting of the delays.
High Pass Filter... (unassigned) Passes frequencies above its cutoff frequency and attenuates frequencies below its cutoff frequency.
Limiter... (unassigned) Limiter passes signals below a specified input level unaffected or gently reduced, while preventing the peaks of stronger signals from exceeding this threshold. Mastering engineers often use this type of dynamic range compression combined with make-up gain to increase the perceived loudness of an audio recording during the audio mastering process.
Low Pass Filter... (unassigned) Passes frequencies below its cutoff frequency and attenuates frequencies above its cutoff frequency.
Notch Filter... (unassigned) Greatly attenuate ("notch out") a narrow frequency band. This is a good way to remove mains hum or a whistle confined to a specific frequency with minimal damage to the remainder of the audio.
Nyquist Prompt... (unassigned) Brings up a dialog where you can enter Nyquist commands. Nyquist is a programming language for generating, processing and analyzing audio. For more information see Nyquist Plug-ins Reference.
Spectral edit multi tool (unassigned) When the selected track is in spectrogram or spectrogram log(f) view, applies a notch filter, high pass filter or low pass filter according to the spectral selection made. This effect can also be used to change the audio quality as an alternative to using Equalization.
Spectral edit parametric EQ... (unassigned) When the selected track is in spectrogram or spectrogram log(f) view and the spectral selection has a center frequency and an upper and lower boundary, performs the specified band cut or band boost. This can be used as an alternative to Equalization or may also be useful to repair damaged audio by reducing frequency spikes or boosting other frequencies to mask spikes.
Spectral edit shelves... (unassigned) When the selected track is in spectrogram or spectrogram log(f) view, applies either a low- or high-frequency shelving filter or both filters, according to the spectral selection made. This can be used as an alternative to Equalization or may also be useful to repair damaged audio by reducing frequency spikes or boosting other frequencies to mask spikes.
Studio Fade Out (unassigned) Applies a more musical fade out to the selected audio, giving a more pleasing sounding result.
Tremolo... (unassigned) Modulates the volume of the selection at the depth and rate selected in the dialog. The same as the tremolo effect familiar to guitar and keyboard players.
Vocal Reduction and Isolation... (unassigned) Attempts to remove or isolate center-panned audio from a stereo track. Most "Remove" options in this effect preserve the stereo image.
Vocal Remover... (unassigned) (Legacy effect) Attempts to remove center-panned vocals from a stereo track. The output from this effect will always be mono. Help text is available from within the dialog.
Vocoder... (unassigned) Synthesizes audio (usually a voice) in the left channel of a stereo track with a carrier wave (typically white noise) in the right channel to produce a modified version of the left channel. Vocoding a normal voice with white noise will produce a robot-like voice for special effects.

Contrast... Ctrl + Shift + T   Extra Analyzes a single mono or stereo speech track to determine the average RMS difference in volume (contrast) between foreground speech and background music, audience noise or similar. The purpose is to determine if the speech will be intelligible to the hard of hearing.
Plot Spectrum... (unassigned) Takes the selected audio (which is a set of sound pressure values at points in time) and converts it to a graph of frequencies against amplitudes.
Find Clipping... (unassigned) Displays runs of clipped samples in a Label Track, as a screen-reader accessible alternative to View > Show Clipping. A run must include at least one clipped sample, but may include unclipped samples too.
Beat Finder... (unassigned) Attempts to place labels at beats which are much louder than the surrounding audio. It's a fairly rough and ready tool, and will not necessarily work well on a typical modern pop music track with compressed dynamic range. If you do not get enough beats detected, try reducing the "Threshold Percentage" setting.
Regular Interval Labels... (unassigned) Places labels in a long track so as to divide it into smaller, equally sized segments.
Sample Data Export... (unassigned) Reads the values of successive samples from the selected audio and prints this data to a plain text, CSV or HTML file. Further information may be added as a "header" at the top of the file.
Silence Finder... (unassigned) Divides up a track by placing point labels inside areas of silence.
