If your music sounds different on the stores to the original audio file you uploaded, there are a few reasons why that may be and what you need to check.
Audio file requirements to distribute music to stores
When we deliver audio files to our partner stores like Spotify, Apple Music and Deezer, there are requirements all audio files must meet. They must be:
- Uncompressed WAV or FLAC files (we recommend FLAC files, as they are often less corrupt)
- 2 Channel Stereo
- Sample size: 16 bit
- Sample rate: 44.1 kHz
Why does my audio sound different on the stores?
Every piece of audio is sent to stores in this format. But if you think there’s something a bit off with the way your music sounds on the stores, it could be for any of the below reasons.
- The wrong or master version has been uploaded to Spinnup. Make sure you double, triple, even quadruple check you are uploading the right audio when setting up your release. We recommend adding FINAL to the file name of your latest mix or master.
- The audio file uploaded has different requirements to the ones set out above. If it’s not the right sample size or rate, for example, it can affect how the audio sounds on the stores.
- The stores have compressed and converted the files for previewing and streaming. But if this is the case, the difference would be minimal and is corrected when the listener downloads or streams the full version of the track
How do I fix the sound?
- The only way to fix audio issues is by taking down your release and reuploading the release with the correct audio files
