Time Shift


Time Shift Time Shift is a free DigiRack™ AudioSuite™ plug-in that delivers high-quality time stretching and pitch shifting for all Pro Tools® and Avid DNA ™ systems. Equipped with four distinct algorithms, Time Shift lets you tailor the processing to different types of source material. Choose Polyphonic to change a guitar or keyboard performance, or a full mix. Select Monophonic if you’re altering vocals or solo instruments. Pick Rhythmic to compress or stretch a loop. Or use Varispeed when you’re converting the sample rate of an audio file.

Time Shift offers multichannel, multi-input phase-coherent processing so you can modify multi-tracked performances while maintaining the phase relationship between mics and tracks. With a wide range for stretching, compressing, and pitch-shifting, you can achieve anything from mild to extreme results. However you use it, Time Shift is an impressive addition to the free collection of DigiRack plug-ins included with all Pro Tools and Avid® picture systems.

Note: TCE Trim tool and AudioSuite Preview Mode are supported by Time Shift in the Pro Tools HD 7.2 software release and will be implemented in a future version of Pro Tools LE and Pro Tools M-Powered.
