Quantum Audio Time Stretch at Mac App Store analyse

This application allows you to load audio files, and to create a new versions in which the playback speed is changed (time stretching), without affecting the pitch. It is targeted to professional and semi-professional audio/music designers who need a high quality and fast audio time stretching application in their toolbox. Features: - Time stretch any music, track, speech or sound by any amount between 4 times slower and 4 times faster. - The time stretching factor can be specified in many ways: length change, speed change, length from/to, tempo from/to, video FPS from/to, etc. - Five quality settings: - 1 and 2 for quick previews or speech. - 3 (default) for the best trade-off between quality and speed. Faster than real-time on most computers. - 4 and 5 for the more demanding sources. Quality 5 may not run in real-time on all computers and is designed for offline processing. - Use a modern audio time stretching algorithm with transient detection and a transient sensitivity setting. - Support mono, stereo and multi-channel (5.1, 7.1) audio files. Fully preserve the stereo / spatial field. - Load and save WAVE (*.wav), AIFF/AIFC (*.aiff, *.aifc) and AU Sun/NeXT (*.au) audio files, in PCM 16-bit / 24-bit integer, or in 32-bit IEEE floating point format. Also load FLAC, OGG, MP3 and M4A files. - Support sampling rates from 32 kHz to 192 kHz. - Transform multiple audio files simultaneously on multi-core computers. - Integrated mini player to preview the result before it is fully transformed.
