Transpose songs by semitones without changing tempo, with Camelot guidance for the resulting key.
Choose or drop one or more songs, set the key shift, then export the results.

Choose the smallest shift that reaches the target key. Changes of 1 to 3 semitones usually preserve vocals and transients more naturally than large moves.
Select the track’s source key before transposing, then use the displayed target key and Camelot value to check the harmonic result.
A shared batch setting is convenient, but each track reacts differently. Listen to vocals, cymbals, and transients before exporting the selected files.
A semitone is the smallest step in Western music — a shift of +1 or −1 moves a track exactly half a step from its original key. This tool applies any shift from −12 to +12 semitones, lets you preview both versions, and exports when it sounds right.
Drop an audio file (it never leaves your browser), choose the shift or detect the current key first, compare the transposed version with the original, then export in MP3, WAV, FLAC, OGG, or OPUS.
The tempo never changes — transposition always preserves speed. For harmonic mixing, try ±1–2 semitones and check the Camelot target key shown by the tool. Shifts beyond ±5 semitones become clearly audible, so use them deliberately.
The tool resamples the audio to move the pitch, then time-stretches it back to the original speed. The two steps cancel out in duration, so only the key changes while the BPM stays the same.
From -12 to +12 semitones (one full octave up or down). Small shifts of 1 to 3 semitones sound the most natural; larger shifts work for creative edits but noticeably change vocal timbre.
One semitone up equals +7 steps on the Camelot wheel: 8A becomes 3A, and 8B becomes 3B. Select the source key and the tool shows the target key for any shift.
Smaller shifts often sound more natural. Larger shifts are more likely to reveal processing artifacts, especially on vocals, so export WAV or FLAC when you plan further editing.
No. Your files are processed on your device and are not sent to a server.
Processing runs on your device, so export time mainly depends on CPU performance, available memory, and track length; long tracks and lower-powered devices take longer. If export fails, close memory-heavy tabs or apps and try again with the latest browser version. If it still fails, use a computer with more available memory.
