Mixee measures what the generator handed over — spectral edge, dynamics, presence, low end — and sets the chain to match. Check it free, no account.
The analysis runs in your browser — no account, no upload. Mastering needs an email address.
Four findings Mixee measures on every track, with the same functions that analyse your master. No estimates, no rules of thumb.
Udio exports are lossy-encoded. Above roughly 15 to 16 kHz there is nothing left — no noise, no content, nothing. Mixee measures that edge and therefore knows an "air" boost up there would only amplify emptiness.
Generator output frequently arrives heavily compressed already. A master that puts another compressor on top does not make it louder, it makes it lifeless. Mixee sees it in the crest factor and the loudness range and backs the compression off instead of piling more on.
The band where vocals and snares live often sits above the genre's target curve in AI material — that is the harshness that gets tiring after a few minutes. Mixee measures the excess and cuts exactly as much as it measured.
Sometimes near-mono, sometimes so wide it cancels. Either only shows up on a club PA or a phone speaker. Mixee measures correlation below 200 Hz before AND after the chain and warns you when widening cost mono compatibility.
Mixee does not remove watermarks or AI detection. Since 2 August 2026, Article 50 of the EU AI Act applies: AI-generated content must carry a machine-readable mark, and removing it is prohibited — fines up to €15M or 3% of annual turnover. Anyone advertising exactly that is selling you a risk that lands on you, not on them. You don't need it either: distributors do not reject AI music. What matters is whether your track holds up next to human-produced music — and that is what we work on.
No. Since 2 August 2026, Article 50 of the EU AI Act applies: AI-generated content must carry a machine-readable mark, and removing that mark is prohibited — with fines up to €15M or 3% of annual turnover. Anyone advertising the opposite is selling you a risk that lands on you, not on them.
No. DistroKid and CD Baby even accept MP3, TuneCore requires WAV — rejections are about spam, fraud and impersonation, not about AI as such. Anyone telling you otherwise is selling you a fear. What actually matters is whether your track holds up next to human-produced music.
No. SynthID is Google's scheme; Udio uses its own statistical signature spread across the whole spectrum. Tools advertising "SynthID removal" for Udio tracks are describing something that is not in your file to begin with.
The analysis is free and needs no account. With an account you get 3 free masters as 320 kbps MP3 — upload in WAV, FLAC or MP3. Pro starts at €23/month and adds 24-bit WAV/FLAC, the expert console, stem mastering and no limit.
WAV, if your generator offers it. No chain can bring back what MP3 encoding threw away, and streaming adds another lossy encode on top — two rounds stacked are audible. The free plan accepts WAV and FLAC.
Honestly: mastering does not change arrangement, vocals or mix — it changes tonal balance, dynamics and loudness. What measurably improves is everything a streaming service and a listener read as “properly finished”. What the generator composed stays.
The analysis is free and needs no account. You see loudness, true peak, dynamics and the spectral edge — before you decide anything.
