The Sound Guy has released Backwards Machine, a cross platform plugin that reverses continuous audio in real time.
Backwards Machine includes three effects :
– Reverse Playback — Reverses and overlaps snippets of the incoming audio, to produce an ongoing backwards effect
– Forward Backwards — Smoothly cross-fades between forward and backward versions of the incoming audio
– Reverse Repeat — Plays snippets of the input audio backwards, twice; the second time, a slight vibrato is added
Backwards Machine supports VST and Audio Unit formats for Macintosh OS X (Universal for PPC and Intel) and is available for $35.00.
