Audacity includes an excellent “Change Tempo” effect which can stretch the length of the selected audio without altering the pitch. The effect includes the ability to specify the required new length, but this option is not available when using the effect in a Macro, or with Scripting. Setting the target length in a Macro Audacity … Continue reading Stretching audio to length
The most basic way to copy a list or an array is simply to assign a new variable with SETQ or SETF, but this may behave in unexpected ways. Let us look at an example: Try running the above in Audacity’s Nyquist Prompt effect (use the Debug button to see the output), and you may … Continue reading Copying lists and arrays
One thing that is quickly learned about Audacity, is that it is NOT a DAW* (digital audio workstation), and is NOT a wave editor. It is a full featured multi-track audio recorder and editor. When “opening” an audio file for editing, the file itself is never modified by Audacity – the audio data is copied … Continue reading Editing and Overwriting an Audio File
A simple “tuning fork” plug-in for Audacity, specifically for tuning a ukulele. This plug-in just generates a tone of the specified note, which is basically what a tuning fork does, except that a real (mechanical) tuning fork is restricted to just one frequency, whereas this plug-in allows you to select the required note. Ukuleles are … Continue reading Ukulele Tuning Tones
Sometimes we may want to be able to quickly find extreme peaks in a recording so that we can treat them in some way. Often we can find the peaks easily by just looking at the waveform. In the example below, we can clearly see that there is a large peak in the left channel … Continue reading Label Peaks
Sometimes we may want to fade-in or fade-out an effect rather than have it start and end suddenly. This article looks at how we can do this automatically within an effect. The way that we would do this manually is by duplicating the track, applying the effect to the duplicate, then crossfading the two tracks … Continue reading Fading an effect in and out
Since the release of Audacity 3.0.3, the Audacity team have made Audacity for Linux available as an AppImage, in addition to the usual binaries for Windows / macOS and source code. This is good news for Linux users, though there are currently some caveats that users need to be aware of. What is an AppImage? … Continue reading Audacity AppImage (Linux)
Audacity has the ability to export label tracks as a text file, and/or import labels from a text file. More information about this is available in the Audacity manual. A limitation of this feature is that it is not available to use in batch processing. There is a macro command ImportLabels: but it only opens … Continue reading Import Labels
Personally I have many reservations about adding watermark / spoilers to tracks, though there are a few situations where such techniques may be useful. The basic idea of adding a spoiler to a song is to incorporate additional audio so that the track cannot be easily distributed or used without authorisation, but remains sufficiently intact … Continue reading Audio Spoilers (“Watermark”)
This is essentially a bug fix release. The headline changes: Made it harder to accidentally create loop regions when attempting to use Timeline Quick Play. Added snap guides when resizing clips. Added new default shortcuts Shift+L (set loop to selection) and Alt+Shift+L (Clear Loop). Re-added selection and quick play indicators in the timeline. Improved performance, … Continue reading Audacity 3.1.3 released
