Listen for less low-end masking, clearer vocal presence, and more high-frequency detail.
Upload a finished stereo mix. Burnish checks whether mastering can meaningfully help, warns you when the source is the problem, and asks whether you want balance, clarity, or warmth. Then it masters the intact mix and lets you hear the result.
Switch between Source and Burnish while the clip plays. These comparisons are loudness-matched so you can judge tone, dynamics, and translation instead of simply preferring the louder file.
Listen for less low-end masking, clearer vocal presence, and more high-frequency detail.
Listen for controlled low-end weight, preserved rock transients, and restrained tonal refinement.
Listen for smoother sibilance, retained bass warmth, and recovered presence and air without brittleness.
Each comparison is a new Burnish master of a previously released song. It is not represented as the master previously delivered to DSPs.
The composition got good. The audio engineering did not always follow. Burnish checks every source for the mud, harshness, missing air, and flattened dynamics that often survive the export.
AI models pile energy where laptops sound thick. On earbuds and in cars it becomes a wall that buries everything.
Upper-mid presence pushed to feel exciting on first listen: and exhausting thirty seconds into good headphones.
Trained on compressed data, the models hard-cut the top. The shimmer that makes a mix breathe is missing.
No distance between an intimate verse and a chorus that should lift. A limiter on a flat source just gets louder.
Send the MP3, WAV, or FLAC you already listen to. Your finished stereo mix stays intact.
Review what mastering can improve and what the source may limit. If the file already looks finished, Burnish tells you and does not charge.
Choose Balanced, Clarity, or Warmth. You define the intended result; Burnish computes the safe processing from the analysis.
Hear Source versus Master at the same playhead, then download the verified 24-bit WAV and its report.
Every Burnish master runs nine release-grade checks before the file is written. Fail a critical one and the pipeline reverts, backs off, and tries a lighter touch. The master doesn't exist until it passes.
No clipping slips through. No over-limited transients. No stereo trick that collapses to mono on a phone speaker. The numbers are the contract.
Every master ships with a full report: before and after for every metric, which stages fired and why, which were skipped, and exactly which checks it passed.
See which corrections fired, by how much, and which were skipped because the source was already in range.
Specific moments where a problem was detected: and whether it was auto-fixed or flagged for you.
If vocal clarity is low because the bass-to-presence gap is 15 dB, you'll know: the problem is the source, not the master.
See what you can try, control, and inspect. Then let your ears decide.

*Not publicly documented means we did not find a customer-facing processing summary or check-results report in the sources linked above. It does not mean the service lacks internal analysis or quality checks. Features and plan availability can change.
You choose Balanced, Clarity, or Warmth. Burnish turns that direction into measured processing, applies only helpful changes, and verifies the finished result.
