TIME FACTORY II

Zynaptiq TIME FACTORY II is a Mac OS X standalone application for precise audio time stretching and pitch shifting—not a Windows VST plugin. It lets you adjust duration and pitch independently, whether you’re matching a loop to a new tempo, transposing a track, converting film audio between frame rates or slowing music down for transcription. Five algorithms—MPEX 2, MPEX 3, ZTX, quickStretch and ClearScale—offer different processing approaches to suit your material, with an emphasis on fidelity and accurate timing. Formant shifting and correction provide further control over tonal character. Batch processing handles multiple files, while phase-synced support covers mono, stereo and multichannel audio at sample rates up to 384 kHz. Set target lengths using BPM, FPS, time, percentages or sample frames. It suits producers, remixers and post-production editors who need dedicated offline processing.
