How it works. Real-time playback uses SoundTouch's WSOLA algorithm — the same time-domain pitch+tempo engine used by djay Pro, Mixed In Key, and Virtual DJ. Transients (drum hits) stay sharp, and pitch + tempo can be changed independently with no cross-talk. Export bakes the entire file through the same engine offline, then encodes to WAV. For musical shifts up to ±7 semitones the result is clean; beyond that any algorithm shows formant shift on vocal material. Audio converter if you want to then convert to MP3.
