If your file is not already a WAV or FLAC you can convert your files using a software or website of your choice. We recommend using Online Audio Converter, which is an easy to use website for you to upload and convert your audio files.
Simply select your file in Step 1, choose which file type you would like to convert to in Step 2, and click ‘Convert’!
Alternatively you can use editing software such as Audacity, which is a program you must download to your computer, to easily edit and save your audio files in the correct format.
It’s important that you properly convert your files and don’t just change the file extension to .wav or .flac because if you do this your files will not be properly converted and will therefore be rejected by the stores.
