Transform Audio

Changes the tempo, pitch, and playback speed of a source audio file, saves the result as a new file, and plays it if required. Transformers are registered in Settings > Audio Transform. This action has no command field.

Audio Transform

Select the audio transform to use.

Source File

Select the source file from the files uploaded to the project. Only the WAV format can be used, and a sample file (sample.wav) is set by default.

Source Type

Select whether the source audio is Speech (default) or Music. Choosing the matching type improves the transform quality.

Tempo Change (%)

Changes the tempo (beat) in the range -95 to 5000%. 0 is the original speed; positive values are faster and negative values slower (for example, 100 is twice as fast and -50 is half speed). The pitch is preserved.

Pitch Change (semitones)

Changes the pitch in the range -60 to 60 semitones. A semitone is the pitch difference between a white key and the adjacent black key on a piano.

Speed Change (%)

Changes the playback speed in the range -95 to 5000%. Unlike tempo, the pitch changes with it, like changing the rotation speed of an LP record (for example, 100 plays twice as fast and one octave higher).

Output File Path

Enter the path to save the transformed WAV file, or pick it in the file browser.

Auto Play

Select whether the transformed audio is played immediately. The default is on.

Wait for Completion

Select whether the action stays running until playback ends. The default is on. Displayed only when Auto Play is on.
