Audacity Dereverb Plugin -

While the exact source code is not explicitly documented as a standalone academic paper, the plugin operates on principles common in dereverberation:

The DeReverb plugin in Audacity is a powerful tool for reducing reverberation in audio recordings. Reverberation, or reverb, is the persistence of sound after a sound source has stopped, caused by repeated reflections of the sound wave off surfaces. While some amount of reverb can add depth and character to a recording, excessive reverb can make audio sound muddy, distant, or unprofessional. audacity dereverb plugin
