Shift the pitch of songs or voice recordings up or down without changing speed.
Shift the pitch of vocal recordings, backing tracks, and instrument stems by -12 to +12 semitones without changing the BPM or overall song duration.

Transpose backing tracks and vocal stems without speeding up or slowing down rhythm.
How to Use
Select songs, vocal stems, or instrument recordings to transpose into a new musical key.
Transpose pitch by exact semitones or fine-tune cents (such as 432 Hz concert pitch) while locking tempo.
Export your newly pitched audio file ready for singing practice or music production.
Transposed Stem Ready
Matched to Vocal Range
Upload your backing track or vocal recording, and use the Pitch slider to shift the key up or down in musical semitones (-12 to +12 semitones equals a full octave). This lets singers adjust accompaniment tracks to match their natural vocal range without changing the song tempo.
No. The pitch shifting engine operates independently of tempo. Shifting a song up by +2 semitones or down by -3 semitones preserves the exact BPM (beats per minute) and song duration.
Yes. In addition to full semitone steps, you can make fine adjustments in cents (1 semitone = 100 cents) to calibrate instruments recorded in non-standard tunings (such as 432 Hz vs standard 440 Hz).
