Realstretch is a live realtime implementation of the Paulstretch audio time-stretch effect. This is the first live realtime implementation of time-stretching as an audio effect that I know of. A modified buffer input method was used in order to compensate for the fact that the output of a time-stretcher is longer than the input and allows it to run continuously. The modified buffer system is paired with the Paulstretch time-stretch algorithm for creating live, epic time-stretches.

Video demo:

Pre-compiled versions of the plugin are available on the GitHub repository.
NOTE: For best performance, it may be necessary to increase your DAWs buffer size.
