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
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)
Whether synchronising an audio recording with a video recording, or synchronising recordings made from each side of a zoom / Skype / telephone conversation, synchronising multiple recordings is a fairly common task. To aid accurate synchronisation, a clapperboard (or simply a couple of hand claps) at the beginning of the recording can provide clear visual … Continue reading Align Tracks
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
This is an experimental “proof of concept” plug-in for FM encoding and decoding. It was written as a bit of fun for the Audacity community – a competition in September 2016 for Audacity users, developers and support crew. The plugin can be download here: Installation Instructions: For the current version of Audacity, please see HERE … Continue reading FM Encoder Decoder
Audacity includes a wide range of built-in effects, but surprisingly there is no distortion effect. Time to remedy that… Here is a simple distortion effect with 10 types of distortion. Each preset modifies the shape of the waveform in its own particular way. There is also a slider control to set the amount, or “drive”. … Continue reading Distortion Effect
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? (Compiled vs Interpreted languages)
This little plug-in is a bit of fun. It is a distortion plug-in effect that simulates a kazoo. To use it, record yourself humming, then apply the effect. Some interesting sounds can be made by applying the effect to other sounds, such as guitar or keyboard recordings. Right click to save kazoo.ny (For Internet Explorer … Continue reading Kazoo Effect
Since version 4 Nyquist plug-ins, the global variable that passes the track audio from Audacity to Nyquist changed from S to *TRACK*.
For mono tracks …
