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.
