Audio File Requirements
Submitting high-quality audio files ensures your music sounds great on every streaming platform. Here are the requirements and best practices.
Accepted Formats
Recommended Specifications
- Sample Rate: 44.1 kHz (CD quality) — the industry standard
- Bit Depth: 16-bit minimum, 24-bit preferred
- Channels: Stereo (2-channel). Mono is acceptable for spoken word
- Loudness: Master to approximately -14 LUFS integrated for streaming. Avoid over-normalising.
Common Audio Issues That Cause Rejection
- Clipping/Distortion: Audio that peaks above 0 dBFS will be rejected
- Silence: Tracks with more than 10 seconds of silence at the start or end
- Low bitrate WAV: Files below 320 kbps are not accepted
- Corrupt files: Files that cannot be decoded or played back
- Mismatched file: Uploading a different song than the one named in the metadata
