Aligning Multiple Tracks

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

Binding keys to vertically zoom 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”

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)

In this example the length of the selected audio was 599.999 seconds and I wanted to stretch it to 600 seconds duration.The durations may be … Continue reading Changing the speed and length very accurately

Are Nyquist Plug-ins slow? (Compiled vs Interpreted languages)

It is a common misconception that Audacity’s Nyquist plug-ins must be slow because they are written in an interpreted programming Language. Nyquist is an interpreted language, meaning that it runs directly from the code rather than being compiled first, but the inner loops of many DSP functions are pre-compiled in highly optimised compiled C code. … Continue reading Are Nyquist Plug-ins slow?
