A semitone is the smallest interval in Western music — the distance between adjacent piano keys. +12 semitones = one octave up, -12 = one octave down.

How is this different from nightcore?

Nightcore speeds up AND raises pitch together for a specific effect. Pitch Shift lets you change pitch independently without changing speed.

Can I use this as a voice changer?

Yes. Shifting pitch up (+3 to +5 semitones) creates a higher-pitched voice. Shifting down (-3 to -5) creates a deeper voice.

Pitch Shift

Change the pitch of audio up or down by semitones. Raise pitch for chipmunk effects, lower for deep voice. Optional speed preservation.
