What's wrong with the sound of generated tracks
Music generators output a track that's already mixed and compressed, and they share the same weak spots. Put regular mastering on such a track and the compressor and limiter raise all the artefacts along with the music.
- “Metallic ring” and “rustle” at 3–11 kHz: ringing cymbals, glassy sibilance in the voice — traces of the neural codec.
- A dull top: almost nothing above ~16 kHz, like a heavily compressed MP3 — the track sounds “airless”.
- Flat drums: the mix is already squashed, hits are smeared into the mass and don't punch.
- Hiss in silence and tails, mush in the low mids, bass wandering across the stereo field.
What AI mode does
A “repair” block goes in front of the regular mastering chain. It carefully removes noise above 7 kHz, brings back drum attack (a transient shaper compares fast and slow envelopes and emphasizes the start of each hit) and tames the harsh “metallic” bands only when they flare up. After that, compression is gentler than usual because the track is already compressed. An exciter rebuilds harmonics above the cutoff up to 20 kHz, and the bass is summed to mono.
- AI track repair: a bit of everything: remove metallic artefacts and hiss, bring back drum attack, rebuild air on top.
- Bring it to life: focus on liveliness: much brighter drum attack, a solid low end, an open top, softer compression.
- Remove metallic ring and hiss: for “ringing” generations: deeper taming of 3–11 kHz, stronger noise clean-up, a softer top.
- Natural vocals: a generated voice without the “glass”: softer sibilance and harshness, more body, cleaner low mids.
How to get the best result
Download WAV from the generator, not MP3: in an MP3 some artefacts are already baked in. Compare “Repair” and “Bring it to life” on one excerpt with loudness matching. If it rings a lot, add “Remove metallic ring”; if it's a song, “Natural vocals”. AI mode works with any genre and character in the builder.
Honest limits: automatic mastering won't rewrite a generated track. It noticeably reduces artefacts and brings life back into the sound. For a big-budget release, it's better to split the track into stems and mix it again.
FAQ
Does it work for Suno v4/v5 and Udio?
Yes. Generators produce similar artefacts, so AI mode is universal. Only the amounts differ: choose a variant by ear in the A/B comparison.
Can I send an AI track to a streamer?
Yes. Choose the “AI” genre in the submission form — the streamer and viewers immediately see the track is generated, and in the charts it goes into its own category.
How much does it cost?
Previews are free: up to 30 variants a day (a 30-second excerpt). Full masters: the first 5 tracks are free, then 40 Notes per track. Notes are Stream-Q's bonus currency: you earn them for tracks rated on streams and other activity on the site; they can't be bought.
What if the mastering fails?
If a render fails, or you cancel a job while it's still queued, the free credit or the Notes you spent come back automatically.
What format will I get?
24-bit WAV (at the source sample rate, no lower than 44.1 kHz) for distribution and 320 kbps MP3 to play on a phone or send in a chat. Files are kept for 30 days; the loudness figures stay in your history.
Who will hear my track?
Nobody but you: the files are private and can only be downloaded from your account. The source is deleted 7 days after it was last used, previews after 3 days.
Why doesn't a loud master sound louder than others on Spotify?
Spotify, YouTube, Yandex Music and Apple Music normalize loudness (to about −14 LUFS, Apple to −16). A track that's too loud just gets turned down, and the dynamics squashed by the limiter don't come back. That's why “Streaming −14” is a sensible default, and “Club −8” is for DJs and systems without normalization.
