Audio File Specifications

The right export settings ensure your music sounds its best and won't be rejected at distribution.

Recommended export settings

Format
WAV or AIFF

Lossless formats are preferred by all major distributors. FLAC is also accepted.

Sample rate
44.1 kHz

The CD standard. 48 kHz is fine for sync/film but unnecessary for streaming.

Bit depth
16 or 24-bit

24-bit preserves more dynamic range from your session. 16-bit is fine for streaming.

Channels
Stereo (2-channel)

Mono files are accepted but will be upconverted by most DSPs.

MP3
Not accepted

Distributors require lossless source files. Never submit MP3 or AAC as masters.

If your DAW project is at 48 kHz or 96 kHz, export at that rate and let the mastering process (or your distributor) handle sample-rate conversion. Avoid converting yourself unless your mastering engineer has instructed it.

Loudness targets

Streaming platforms normalise playback loudness. Mastering too loud wastes dynamic range and won't give you an advantage — it will be turned down.

Spotify
−14 LUFS

Normalises to −14 LUFS integrated. Louder masters are turned down.

Apple Music
−16 LUFS

Uses Sound Check normalisation. Lossless tier displays dynamic range.

YouTube
−14 LUFS

Consistent with Spotify target.

Tidal
−14 LUFS

Masters at −14 LUFS integrated.

True peak
−1 dBTP

Keep true peak under −1 dBTP to prevent inter-sample clipping after encoding.

For most release types, master to −14 LUFS integrated with a true peak of −1 dBTP. This is the sweet spot for streaming. Classical and jazz benefit from a slightly lower target (−16 to −18 LUFS) to preserve dynamic range.

Naming your files

Most distributors accept any filename, but it's good practice to use consistent naming:

  • Use the track title exactly as it appears in your metadata
  • Avoid special characters: stick to letters, numbers, spaces, hyphens
  • Include the track number if submitting an album (e.g. 01_TrackTitle.wav)

Common reasons for rejection

  • Clipping or digital distortion in the audio
  • Silent sections at start or end longer than 5 seconds
  • MP3, AAC, or other lossy formats submitted as masters
  • Sample rate or bit depth mismatch with the stated metadata
  • Unlicensed samples or copyrighted material
  • Mono files submitted for a stereo release (some distributors reject this)
