Reversinator is a free glitch VST plugin developed by ndc Plugs. Compatible OS(s): Windows, macOS.
Reversinator, a “simplistic realtime audio-reversing plugin”.
The input audio is read into a 88200-sample buffer, which has two read pointers (going in the opposite direction of the write pointer), half the buffer apart. The sound from each pointer is mixed according to a raised cosine type envelope, to ensure the volume is constant, and that you never hear the discontinuity between the previous data and the new data being written in.
