Before uploading your music on SunoDistro, it is important to prepare all the required files in the correct format. Having the right files ready helps ensure faster approval, avoids rejection, and makes the upload process smooth and stress-free—especially for first-time artists.

This guide explains all required files for music upload on SunoDistro, what formats are accepted, and best practices to follow.

1. Audio File (Required)

The audio file is the most important part of your release.

Accepted Audio Formats

• WAV (recommended)

• High-quality MP3

Audio Guidelines

• Audio must be clean and professionally mastered

• No distortion, clipping, or background noise

• No long silence at the beginning or end

• Audio must be the final version

Do not upload:

• Demo or unfinished tracks

Each track must be uploaded as a separate audio file.

3. Metadata Information (Required)

Metadata is the information that describes your music on platforms.

You must provide:

Only provide ISRC or UPC if your music was previously released.

6. Artist & Label Details (Required)

You must select or add:

• Artist profile

• Label name (if applicable)

Artist name spelling must remain consistent across all releases to avoid duplicate profiles.

Common File Preparation Mistakes to Avoid

Avoiding these mistakes ensures faster approval.
