Questions
What does Burnish do to my track?
It measures your mix, repairs common problems, then masters to the loudness streaming platforms expect. Every move it makes is printed on a before and after report, so nothing is a black box.
Does it work on Suno and Udio songs?
Yes. AI generators leave a signature that shifts from version to version: a cutoff that drops the air off the top, a hazy upper range, low-mid mud, and a narrow stereo image. Burnish measures what your file actually shows and rebuilds only what it finds, before it masters.
How much does it cost?
You master and preview for free. You buy a credit only when you want to download, and one credit unlocks one master in every format, forever. There is no subscription.
What formats do I get?
MP3 320, 16-bit WAV, and 24-bit HD WAV, all from the same unlocked master.
Will my track be loud enough for Spotify and Apple Music?
It hits your chosen loudness target and holds true peak to a safe ceiling, verified on your file at 4x oversampling. The measured numbers are on the report.
