Frequently Asked Questions
What is the range of pitch shifting?
The tool supports shifting from -12 semitones (one octave down) to +12 semitones (one octave up), in whole-semitone steps.
Does this change the tempo or duration?
Yes. Pitch shifting works by resampling the audio, so the shifted file gets a different duration — higher pitch shortens it and lower pitch lengthens it. The playback speed changes accordingly.
Can I shift pitch for karaoke practice?
Yes. Shifting the key of songs is great for matching your vocal range during practice.

Are these media tools free?
