## What is Burnish?

Burnish takes a song you made with an AI music tool and makes it sound finished.

AI generators leave marks. The top end stops dead around 16 kHz. There is a haze in the mids and a lump of mud around 350 Hz. The stereo image is narrow. 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. All of it happens on your iPhone or iPad. No upload, no account, no waiting in a queue.

WHAT YOU GET

Repair first, then master. Burnish rebuilds the missing top end, clears the mud, and opens the stereo image before it touches loudness. Most mastering apps skip this part.

Six dials. Intensity, tone, bass, width, dynamics, de-ess. Turn one and Burnish runs the full chain again in seconds. Free, as many times as you like.

Reference match. Pick a song from Files. Burnish reads its tone and loudness and shapes your track to sit beside it.

A fair A/B. Before and After play at the same loudness, so you judge the tone and not the volume.

It shows its work. Every EQ move, every dB of compression, the limiter's numbers. You can read exactly what changed and why. No black box.

Loudness targets that mean something. Streaming, YouTube, Dynamic, or Club. True peak held at -1 dBTP so nothing clips after upload.

18 genre profiles. R&B, hip-hop, pop, rock, house, techno, drum and bass, reggaeton, country, metal, ambient, jazz, classical and more. Each one tuned by ear, not by a preset name.

Share the before and after. A 15 second vertical video with the spectrum, the score, and the numbers. Made for Reels, Shorts and TikTok.

Also a plugin. Burnish runs as an AUv3 effect inside GarageBand, Logic Pro for iPad and other AUv3 hosts, so you can hear the master while you arrange.

Export a 24-bit WAV, ready for any distributor.

HOW IT IS PRICED

Your first master is free, no card, no sign-up. After that, one purchase unlocks the app for good. No subscription. No monthly fee. No credits.

PRIVACY

Your music never leaves your device. Burnish does not upload audio, does not train on your songs, and does not need an account.

Burnish is made by a musician who got tired of paying a subscription to master songs that still sounded like demos. It works on any track, AI-made or not.

## Version history (last 5 releases)

### 1.4 — 2026-09-21

The condition check now measures the hiss the newer generators leave behind. Some of them no longer cut the top end off at all, so a track could come back reading clean while still being half noise up there. It now tells you how much of the top end is hiss rather than music, and counts it in the score.

The before and after video only says a master is release-ready when every check passes, not just the peak.

Product page links open where they point: a link for one genre starts your next master on that genre, and a demo link goes straight to the demo track.

On iPad the app says iPad. The promise that nothing leaves your device named the wrong device.

First master is free. Pay once. No subscription. Nothing leaves your device.

### 1.3 — 2026-09-19

The repair now takes the hiss out of the top end. It turns down only the noise-like part, never the notes or the hits, and it only runs when the top end is mostly hiss. We picked the setting by ear, in a blind test on real AI-generated tracks.

Every master gets a release check. Loudness, true peak, sample rate, length, the ending and mono safety, each read against what streaming services and distributors look at on upload. If something would get your track bounced, it tells you what to fix.

The share video now plays the loudest part of your song as one take, switching from before to after at the same spot. It shows what Burnish found, then what it fixed.

On a wide screen the results sit in two columns, the curve beside the dials. Links to burnishaudio.com open straight in the app.

First master is free. Pay once. No subscription. Nothing leaves your device.

### 1.2 — 2026-09-09

Master a whole record. Pick the tracks of an EP or album and Burnish masters them in order with one genre profile and one loudness target, on your device. The sheet shows every track's loudness and true peak side by side, and the spread between them, so the quiet ballad is a choice and not a surprise. Export all the WAVs in one go. Part of the one-time unlock, no extra purchase.

A Burnish folder in Files. Exported masters and album tracks now have a home you can find, and you can pick tracks from it.

First master is free. Pay once. No subscription. Nothing leaves your device.

### 1.1 — 2026-09-06

Your master, your call. Six dials now sit under the results: intensity, tone, bass, width, dynamics, de-ess. Turn one and Burnish runs the whole chain again on your phone. Free, every time.

Match a reference. Pick a song you love from Files. Burnish reads its tone and loudness and masters yours to sit next to it.

A fair A/B. Before and After now play at the same loudness, so you hear the tone change instead of "louder sounds better."

Share the proof. A 15 second before and after video, ready for Reels, Shorts and TikTok. Spectrum, score, and the exact dB moves on screen.

See the work. The results screen animates what was repaired: the rebuilt top end, the mud that was cut, the width that came back.

Also in this update: long tracks master safely on phones with less memory, the plugin no longer glitches when you change genre while it plays, and the Shortcut recognizes your unlock on a fresh install.

First master is free. Pay once. No subscription. Nothing leaves your device.
