TIME FACTORY II is a professional Mac OS X application designed for high-quality audio time stretching and pitch shifting. It offers a selection of acclaimed algorithms including MPEX, ZTX, and ClearScale, enabling precise adjustments of audio duration and pitch independently across a wide range of stretch ratios. The software supports mono, stereo, and multichannel files with sample rates up to 384kHz, preserving metadata across popular audio formats. This makes it ideal for tasks such as frame rate conversion for film sound, music tempo and pitch adjustments, remixing, sound design, or slowing down audio for transcription.

User-friendly operation allows for quick processing by simply dragging files into the application, setting the desired stretch or shift amount, and initiating processing. Stretching factors can be entered in various units such as target duration, percentage change, BPM, FPS, or sample frames, accommodating different workflow preferences. TIME FACTORY II ensures exceptional timing precision, even with very long audio files, maintaining sync and avoiding common artifacts like flanging or transient distortion. Its suite of five distinct algorithms offers flexibility to select the optimal processing method tailored to the material and desired outcome.

The application excels in handling complex multichannel audio with phase-synced processing and supports all major file formats including AIFF, WAV, BWF, and SoundDesigner II, while maintaining metadata integrity. Its industrial-grade batch processing engine allows users to automate high-quality time stretching across many files efficiently, aided by factory presets for frequent tasks like frame rate conversion and the ability to save custom settings. TIME FACTORY II combines precision, compatibility, and speed, delivering a powerful solution trusted in professional audio and post-production environments.
