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
I had need to transfer audio clips from an Audacity project to another program. While Audacity supports exporting multiple files based on labels, or exporting each audio track as a separate file, it does not provide a convenient way to export clips as separate files. To compensate for the absence of this feature, I wrote … Continue reading Export Clips
Audacity provides a basic noise generator for creating new tracks with a choice of noise colours, but sometimes we want more specific noise types, and we want to mix them in with existing audio. Here is a plug-in that provides 4 kinds on noise, and mixes the noise into the selected audio. Noise Types Controls … Continue reading Adding noise to a track
“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”
The De-Clicker and De-Esser plug-ins are popular with some audiobook authors. The purpose of the De-Clicker is to remove mouth clicks and similar clicky sounds from the recording, while De-Esser is for reducing excessive sibilance (hissy “s” and “shh” sounds). These plug-ins have horrible code and are only available on the understanding that there is … Continue reading De-Clicker and De-Esser
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
