AudioScience’s TSX time scaling technology can be used independently on any or all audio  playback streams to expand or compress audio in real-time by up to 20%, while preserving pitch and clarity.  TSX can also be used in conjunction with any of the compression formats supported by ASI6000 adapters, including MPEG-1 Layer2 and MP3.

The algorithm is available to Windows software developers through the AudioScience wavX extensions to the Microsoft WAVE API or the AudioScience HPI interface.  Linux developers are able to access it through the AudioScience HPI interface.
