Short answer: remastering suits songs where the arrangement is already settled but the finished track sounds dull, low on energy, or not clear enough. For a safe lift, start with
natural; for more obvious loudness and presence, useboost; when the main problem is transparency, useclarity. It will not rearrange your song for you.
First decide whether you need a remaster at all
| Problem | Better fix |
|---|---|
| Vocals sit too far back, the whole mix sounds dull | Try a remaster first, with a clarity-oriented profile |
| One line of lyrics or one section is weak | Replace the section, don't remaster the whole song |
| Arrangement, tempo or structure is wrong | Remix, extend, or generate again |
| You only want a WAV file | Export WAV directly, no remaster needed |
The three style profiles
| style_profile | What it does | Best for |
|---|---|---|
natural | Most restrained change, keeps the original balance as far as possible | Finished tracks that are already solid and just need rough edges smoothed |
boost | More energy and presence, suited to phone speakers and short video playback | Pop, rock, ads, and songs with a clear beat |
clarity | Emphasizes clarity and separation | Muffled vocals, crowded backing, a mix that needs more transparency |
Don't push variation strength to the maximum straight away
variation_category accepts subtle, normal and high. Start with normal, confirm the direction still matches the original, then raise the strength. Higher strength means a more audible difference from the original, which does not automatically mean better quality.
API call example
curl -X POST "https://www.suno-api.io/api/music/remaster" -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" --max-time 300 -d '{
"model": "suno-v6",
"song_id": "finished_song_id",
"variation_category": "normal",
"style_profile": "clarity"
}'Save the song_id of the two new songs in the response, then poll the song query endpoint until they finish. The remaster request is accepted synchronously, so set your client timeout to 300 seconds or more; if it times out, check your task history first instead of resubmitting immediately.
Recommended listening workflow
- Keep the original fixed and save an untouched reference file;
- Generate two versions first with
normal + boost; - Match the loudness of all three versions, then compare vocals, low end and stereo image;
- If the only issue is dullness, try
clarityon its own; - Once you pick a version, download the WAV and move on to editing or release.
Common questions
Does remastering rearrange the song?
No. It remasters an already finished song for audio quality; arrangement and section problems belong to the relevant editing endpoints.
How do I choose between Natural, Boost and Clarity?
Natural to keep the original character, Boost to add energy, Clarity to improve transparency.
How many songs does one remaster return?
One request returns 2 versions; keep whichever one sounds better in your listening test.
