> Audacity is a free and open-source digital audio editor and
> recording application software, available for Windows, macOS, Linux,
> and other Unix-like operating systems. The project was started in
> the fall of 1999 by Dominic Mazzoni and Roger Dannenberg at Carnegie
> Mellon University, and released on May 28, 2000 as version 0.8.
>
> In addition to recording audio from multiple sources, Audacity can
> be used for post-processing of all types of audio, including effects
> such as normalization, trimming, and fading in and out. It has been
> used to record and mix entire albums, such as by Tune-Yards. It is
> currently used in the Sound Creation unit of the UK OCR National
> Level 2 ICT course.
>
> Audacity does not support instrument VST (VSTi) plugins. There are
> no real time track equalizers or other real time effect slots for
> playback or recording. All such effects have to be rendered after
> recording/import. Audacity does not natively import or export WMA,
> AAC, AC3 or most other proprietary or restricted file formats;
> rather, an optional FFmpeg library is required. ~ [Wikipedia][1]
