Overview

Audio Key Change for Singers transposes an uploaded song by selecting a source and target key or entering an exact semitone adjustment. It preserves the song’s duration and playback speed, with optional vocal formant preservation when supported by the available renderer.

When to use

Adapt a backing track to a singer’s comfortable vocal range.
Create rehearsal or performance versions in a different key.
Test precise pitch changes of up to 12 semitones without changing song duration.

How it works

1Upload an audio file in a supported audio format.
2Choose Key to key and select the source and target keys, or choose Semitone adjustment.
3Set the semitone value from -12 to 12 and an octave offset from -1 to 1 when using precise adjustment.
4Optionally preserve vocal formants, then select MP3, WAV, FLAC, M4A, or OGG Vorbis for the output.

Use cases

Singers preparing backing tracks for a comfortable range.
Bands creating alternate-key rehearsal files.
Music creators making exact pitch-shifted versions for performance tests.

Examples

Singer preparing a rehearsal track

Background

Problem

The backing track needs to be two semitones higher without changing its duration or speed.

How to use

Upload the song, choose Key to key, set the source key to C and the target key to D, enable vocal formant preservation, and select WAV.

Source key: C; target key: D; octave offset: 0; preserve vocal formants: enabled; output: WAV.

2. Lower a full mix by three semitones

Background

A vocal coach wants to give a student a lower version of a complete practice track.

Problem

The song sits too high for the student, but the arrangement must retain its original timing.

How to use

Upload the full mix, choose Semitone adjustment, enter -3, keep the octave offset at 0, and select MP3.
