Audio File Format Requirements

Uploading and Converting Your Music Files for the Best Sound

In this guide, we'll walk you through choosing the best audio file format for your music, what happens after you upload your files, and what your fans can download.


Picking Your Audio File Format

When you're ready to upload your music to Single, we recommend using WAV, AIFF, or FLAC formats. These are known as lossless formats, and they help keep your music sounding great.


What Happens After You Upload

Once you upload your music files to Single, we check them out and do a few things:

  1. We make sure the files are all good and not broken in any way.
  2. We change your files into a few different types (like MP3, FLAC, ALAC, and WAV). This lets your fans pick the format they want when they download your music.
  3. We secure your files we send them over to your store.


How Single Handles Metadata & Encoding

When you're creating a release on Single, we add the information you give us (like your album name and song names) to your music files. This info is called metadata. But keep in mind, if you pick WAV as your file type, it won't have this extra info when your fans download it. So, it'll show up as a plain audio file (like "01-tracktitle.wav").


What Your Customers Download

When your fans are ready to download your music, they can pick from MP3, WAV, FLAC, or ALAC formats. Take a look at how it looks from the customer's side:


Files will download with dashes instead of spaces (like "01-track-title") in the file names. However, when imported into any music player app, the imported music files will contain accurate metadata. This means all the info you added (like the song and album names) will show up.

Please note: WAV and FLAC files don't come with extra info like album art, track info, and album info. If you upload an AIFF file, that extra info won't show up in the final download for your fans.
