This plug-in copies the dynamics (changes in volume level) from a source track and applies it to the audio in the destination track. The source and destination tracks must both be selected, but if only one track is selected then that track is treated as both the “source” of the dynamic envelope and the “destination” … Continue reading Dynamic Mirror
This plug-in is for measuring the highest and lowest peaks in the selected region. It is intended for fairly short selections. Example use cases include precisely measuring the level of noise prior to using dynamic effects such as Noise Gates, or measuring the amount of asymmetry in a waveform. Unlike most other peak measuring tools, … Continue reading Highest and Lowest Peaks
This plug-in extends the capabilities of the Align Tracks plug-in. As with the original version, it requires a synchronisation mark near the beginning of each track (see the description for the previous version). This new version, designed for Audacity 2.4.2 or later, locates the synchronisation mark in the first selected track, then adjusts the positions … Continue reading Aligning Multiple Tracks
A recent feature request for Audacity was for the provision of key bindings to zoom in / out vertically on a track. This feature is already available in a limited fashion from the “Set Track Visuals” macro command. The first step is to create a macro and add the command “Set Track Visuals”. Enable the … Continue reading Binding keys to vertically zoom tracks
“Steganography” from the Greek steganós (concealed) and graphia (writing), is the practice of hiding information within another message or physical object. It could be described as a form of “hiding in plain sight”. There are several different stenanogrphic techniques relating to audio. This article, and the associated plug-in uses one specific technique called Amplitude Modulation … Continue reading Steganography and “Silent Subliminals”
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
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)
This plug-in can be helpful in situations where you have a project that has a lot (possibly hundreds) of labels, and you want to locate one specific label quickly by searching for the label text. While it is perfectly possible to scroll through the Label Editor window and look for the label text, the Label … Continue reading Find Label (plug-in)
Audacity envelopes provide a useful, non-destructive way to modify the volume of the audio, but are rather fiddly to use. Due to the lack of numeric input, it’s virtually impossible to set precise values manually. This plug-in provides a simple way to add envelope control points with precise values. Download Installation: Installation is in the … Continue reading Envelope Control Points
Introduction “Assertions” (or simply “Asserts” are commonly used in many programming languages to help developers read and understand code, and to help to detect possible defects (bugs). An assert is usually a predicate that tests a variable in the program and returns a boolean (true / false) value. In common English, it is like saying: … Continue reading Assertions
