Suno WAV vs MP3: what to export before mastering

Master from the cleanest Suno export you can get. If you limit an MP3, you encode artifacts, then encode again for YouTube. WAV in, 24-bit WAV out, then let the platform make the lossy file.

Why MP3 in is weaker

MP3 already threw away high-frequency and transient data. A limiter makes those holes louder. The result is “brighter” and also more brittle.

What this tool accepts

WAV, MP3, FLAC, and M4A, depending on the browser. Prefer WAV or FLAC. Keep the file under 250 MB and 15 minutes for stable browser processing.

Drop the export into the free mastering workspace. Nothing is uploaded to a processing server.

FAQ

Can I master a Suno share link MP3?

You can try. If you still have the original download, use that instead of a re-ripped stream.
