Backwards Machine is a cross-platform plug-in 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 format for Windows. Occasional gaps in the audio until registered.
