Best Audio Format for Music Distribution

WAV vs MP3 vs FLAC — Which One Should You Upload?

Uploading your music isn't just about clicking the submit button. The audio format you choose can affect sound quality, listener experience and even whether your release gets accepted.

If you're distributing music through SunoDistro, using the correct audio format helps ensure your release reaches streaming platforms with the best possible quality.


🎵 Why Audio Format Matters

Streaming services receive millions of songs every month. Starting with a high-quality master gives platforms the best source before they create their own streaming versions.

💡 Pro Tip:
Always keep your original master file. Never upload the only copy you have.

🥇 WAV (Recommended)

  • Highest quality
  • Lossless audio
  • Preferred by most music distributors
  • Perfect for Spotify, Apple Music and YouTube Music
Recommended: 24-bit WAV, 44.1kHz or higher.

🎧 MP3

MP3 files are much smaller, but they remove audio information through compression.

They're useful for previews and sharing demos, but they should not be your first choice for commercial music distribution.


🎼 FLAC

FLAC is another lossless format that keeps excellent sound quality while reducing file size.

Some distributors accept FLAC, but WAV remains the safest and most widely supported option.
