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)
This plug-in generates a tone at specified intervals into an existing track. This process is sometimes used as a watermark or spoiler to deter unauthorised copying / fraudulent claims of copyright. Before deciding to use watermarks / spoilers, take a few moments to consider: Should I add spoilers to my audio? Types of watermark There … Continue reading Beeper.ny (audio spoiler)
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
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 plug-in is based on the same code as the Variable Tremolo plug-in and was written in response to a request for a plug-in for making Isochronic Tones (Isochronic Beats). For anyone unfamiliar with the term (as I was), Isochronic beats are related to binaural and monaural beats and the idea of brainwave entrainment. At … Continue reading Isochronic Modulator Plug-in
Well it turned out to be more of a challenge than anticipated, but finally it’s here. A Nyquist plug-in that allows envelopes to be created via text entry. This plug-in is basically complete, but requires a bit of tidying of the code. This is a version 3 plug-in and requires Audacity 1.3.x New features in … Continue reading Text Envelope 0.8 beta
