High-quality audio files make sure your music sounds the way you intended on every platform.

## Requirements

| | Requirement |
|---|---|
| **Format** | WAV or FLAC (lossless) |
| **Sample rate** | 44.1 kHz or higher |
| **Bit depth** | 16-bit or higher. 24-bit is recommended. |
| **Channels** | Stereo preferred |
| **Maximum file size** | 2 GB per file |

MP3, AAC and other compressed formats are not accepted. Converting an MP3 to WAV does not restore the lost quality, so always export from your original project or master.

## Other rules

- Upload **one file per track**. The same audio file cannot be used twice in one release.
- Two tracks in the same release cannot have the same title *and* version.
- Remove silence at the start and end of the file unless it is part of the song.
- The audio must match the track information. For example, a track marked "Instrumental" must not contain vocals.

## Uploading

Several files upload in parallel. Keep the page open until every upload shows as complete before you continue to the next step.
