Transposing Audio

This lesson will show you how to transpose audio files so your musicians can rehearse them in the right key.


Our transposer and media player work with MP3, M4A, and AAC file types. If your audio is in a different format, convert it before you add it to your Song in Services. CloudConvert is an excellent online conversion software that's free and easy to use.

Search for a song in the Songs page, and then click the song title.


In your arrangement, select the music note icon in the Files section of the arrangement.



You can also hover over a specific audio file and press 't' on your keyboard, or select the Transpose button that appears.

  1. Use the dropdown to select a file to transpose. Any transposable audio files (mp3, m4a, aac) attached anywhere on the current arrangement will be options.

  2. Listen to the selected file if you need to determine its original key.

  3. Choose the original key of the selected file, and then select which keys you'd like your file in. If you choose a key that does not yet exist on your arrangement, it will be created.

  4. If you want the file name of all your transposed files to be different than your original, edit the base file name.

  5. See which files will be created based on the To key and Name you've specified.

  6. Select which direction each song file will be transposed to. The closest direction, which normally provides the best results, is chosen automatically.

Click Transpose, and your files will go into the queue to transpose.

As your files transpose, you'll see progress at the top of the arrangement tab. When they finish, they'll show up in your file lists.


The further away from the original key you go, the more interesting the transposed file will sound. The speed never changes, and the instruments sound mostly the same. The vocals, however, will start to sound more like chipmunks or monsters the farther you transpose.
