Pitch 'n Time Pro
Pitch 'n Time Pro is a high quality time-stretching and pitch-shifting AudioSuite software plug-in for the Pro Tools platform. It works with all versions of Pro Tools including Pro Tools HD, LE, and M‑Powered.
Pitch 'n Time Pro offers time compression and expansion from a ratio of 1/8 speed through to 8 x speed independent of pitch, and pitch shifting of up to 36 semitones independent of tempo.
The time-stretching and pitch-shifting functions each have three interchangeable panels, ranging from simple fixed ratios to complex tempo and pitch alterations that vary over time. You can even warp the timing of your samples just by placing markers and moving them around.
The tempo and pitch panels can be mixed and matched to suit your application, with real time previewing.
Existing Pitch 'n Time Pro users, with Pro Tools 10.3.5 or higher, can upgrade to Pitch 'n Time Pro 3.0 from their Products page.
