the graphical interface is based on the wxWidgets library.

the results can be saved in a variety of formats provided by the libsndfile library.Īudacity actively uses third-party libraries distributed under different licenses:.

reduction of tracks with different qualitative characteristics (with conversion to the characteristics of the project in real time).

Playback of multiple tracks at the same time (without support for multi-channel audio - only two channels are used during playback, into which all tracks are mixed).

spectral analysis using the Fourier transform with different window shapes.

various types of editing: changing the tempo while maintaining the pitch of the tone, changing the pitch while maintaining the tempo, reducing the noise according to the sample, etc.
