Does pitch shifting change the speed?

No. This tool uses "Time Stretching" technology to change the pitch (key) while keeping the original tempo/speed exactly the same.

A semitone is the smallest step in Western music (e.g., from C to C#). Shifting +12 semitones moves the audio up exactly one full octave.

Can I key-change my karaoke tracks?

Yes! This is the primary use case. If a song is too high or low for your voice, you can shift it by -2 or +2 semitones to find your perfect range.

Does it sound robotic?

Small shifts (±1-4 semitones) sound very natural. large shifts (>7 semitones) can start to sound processed or "chipmunk-like" due to the nature of vocal formants.
