The timing, pitch, and formants of an audio file can be changed independently or together in combination.
Transients must be defined accurately through automatic and manual means to achieve the best results when creating Apple Loops.
Apple Loops depend on the song's key and tempo, automatically conforming when changed.
The Time and Pitch Machine provides detailed control and functions independent of the song's tempo or key.
The Time and Pitch Machine can utilize Harmonic Correction when pitch shifting to preserve the natural resonances of a given sound.
Beat Mapping allows the accurate rescaling of the time grid to a rubato part.
Both Audio and MIDI Regions can be used as the basis for Beat Mapping.
Logic can retain multiple Tempo tracks per song, called Tempo Alternatives, that can be toggled back and forth for comparison.
