Accepted Audio File Formats

SunoDistro accepts the following audio formats:

Accepted Formats

• WAV (Recommended)

• MP3

Both formats are supported, but WAV is strongly recommended for best audio quality and professional results across streaming platforms.

WAV File Requirements (Recommended)

WAV files provide uncompressed, high-quality audio and are preferred by digital stores.

Technical Specifications:

• File format: WAV (PCM)

• Bit depth: 16-bit or 24-bit

• Sample rate: 44.1 kHz

• Channel: Stereo (recommended)

Using WAV ensures better sound clarity and prevents quality loss during encoding by streaming platforms.

MP3 File Requirements (Accepted)

MP3 files are accepted on SunoDistro, but they must meet quality standards.

Technical Specifications:

• Bitrate: 320 kbps (required)

• Encoding: Constant Bitrate (CBR recommended)

• Sample rate: 44.1 kHz

• Channel: Stereo

Low-bitrate MP3 files (128 kbps, 192 kbps, or ripped audio) may result in quality issues or rejection.

Audio Quality Guidelines

Regardless of format, your audio must meet the following quality standards:

• No distortion or clipping

• No excessive background noise

• No silence longer than 5 seconds at the beginning or end

• Proper fade-in and fade-out where necessary

• Balanced loudness without over-compression

Poor-quality audio may be rejected even if the format is accepted.

Loudness & Mastering Recommendations

Although SunoDistro does not strictly enforce loudness limits, recommended mastering settings are:

• Integrated loudness: Around -14 LUFS

• True peak: Below -1 dB

Streaming platforms normalize loudness automatically, so excessive limiting should be avoided.

Embedded Metadata

Do not embed metadata inside the audio file.

Please add:

• Artist name

• Track title

• Lyrics

• Copyright information

directly inside the SunoDistro dashboard during upload.

Embedded metadata can cause processing issues.

Content & Copyright Rules

Your audio file must be:

• 100% original or legally licensed

• Not downloaded or ripped from YouTube, Spotify, or other platforms

• Free from copyright violations

Unauthorized content may lead to rejection.

Before Uploading – Quick Checklist

• WAV (preferred) or MP3 (320 kbps)

• 44.1 kHz sample rate

• Clean, mastered audio

• No embedded metadata

• Original and legally owned content

Conclusion

SunoDistro supports both WAV and MP3 audio uploads, allowing artists to choose what works best for them. However, for the highest sound quality and smoothest distribution, WAV format is always recommended.

Following these audio file requirements helps ensure faster approval and professional playback across all streaming platforms.
