Burnish: AI Audio Mastering

Burnish cleans up AI songs and masters any song, right on your iPhone or iPad. Master and listen free, as often as you like. Pay once when you want to save.

AI generators leave marks. The top end stops dead around 16 kHz. There is a haze in the mids, a lump of mud around 350 Hz, hiss in the highs, and a narrow stereo image. You can hear it on good headphones, and so can the people who decide what gets playlisted.

Burnish finds those problems, fixes them, then masters the track to streaming loudness. If your song has none of them, from a home studio, a phone or a band room, Burnish skips the repair and just masters it. No upload, no account, no waiting in a queue.

THREE STEPS

1. Adjust. Every control changes the sound the moment you move it: Intensity, the Sound Pad for tone and punch, and where the song is headed (streaming, YouTube, club). Turn on Advanced in Settings for bass, width, dynamics and de-ess dials. Slide between Before and After at the same volume, so you judge the sound and not the level.

2. Versions. The Release Kit makes Sped Up, Slowed + Reverb, 15, 30 and 60 second hooks for Shorts, Reels and TikTok, and a seamless loop from your master. Sped Up and Slowed + Reverb are re-mastered and matched to your master's loudness. Every file is named the way distributors want version titles.

3. Save. A 24-bit WAV or AAC file, ready for any distributor.

ALSO IN BURNISH

See what it fixed. A sound check score, the before and after spectrum, and the numbers: loudness in LUFS, true peak held at -1 dBTP.

Master a whole record at once. One genre and one loudness target for every track, so the album plays as one record.

Match a reference. Pick a song from Files and Burnish shapes your track to sit beside it.

18 genre profiles, from R&B, hip-hop and pop to house, drum and bass, country, metal, jazz and classical.

It shows its work. Every EQ move, every dB of compression, the limiter's numbers. No black box.

A plugin too. With Burnish Pro, the Burnish tone runs live on a track in GarageBand and Logic Pro, with Genre, Intensity and Loudness controls.

PRIVACY

Made by a musician who got tired of paying a subscription to master songs that still sounded like demos.
