What is Suno Remaster?
Suno Remaster re-renders a song you already generated so it sounds more finished, without rewriting it. Send the clip_id of an existing Suno clip to suno-ai/remaster and the clip goes back through Suno's remaster model. The lyrics, structure, and arrangement stay as they are. What changes is the production: tone, clarity, and stereo image. Five optional sliders, each from 0 to 1, control the result (freedom, tone, strength, stereo_width, clarity), and tags lets you nudge the style. Each request returns two remastered clips, so you can compare both and keep the better one. It is most useful for older generations that sound thin next to current output.
Key features of Suno Remaster
Four features cover how remastering works.
Same song, new production
The remaster keeps lyrics, structure, and arrangement. Only the production layer is re-rendered, so the track stays recognizable to anyone who heard the original.
Five sliders from 0 to 1
freedom, tone, strength, stereo_width, and clarity each take a value from 0 to 1. Omit any of them to keep the default, so a request can change one thing and leave the rest.
Two versions per request
Every call returns a pair of clips in the same shape as music generation. Compare them by ear, keep one, and use its clip ID for export or further edits.
Optional style tags
Pass tags such as "warm, analog, wide" to steer the remaster toward a sound. Leave it empty to stay close to the original style.
Best for
Older generations
Bring songs made on earlier Suno versions closer to current production quality without regenerating them.
Release prep
Widen the stereo image and raise clarity on a track before it goes to a streaming platform.
Vocal-heavy tracks
Push clarity up on songs where the vocal gets lost in the mix.
A/B choices
Use the two versions from each request to pick a direction before spending time on mastering.
Catalog refresh
Run a back catalog of clip IDs through the same slider settings so the whole set sounds consistent.
Use cases
Add a "Remaster" action to a song library that sends the selected clip_id with fixed slider presets (for example a "wide" preset with high stereo_width) and shows both returned versions side by side. Build a batch job that walks through older clips, remasters each one with the same clarity and tone values, and stores the chosen version for release. After picking a version, export it with the Suno WAV Download API for final mastering in a DAW, or split it with Suno Stems if you want to rebalance parts yourself.

The response contains a task_id. Poll GET /v1/tasks/<task_id> or set a callback_url on the request to receive the two remastered clips when they are ready.
FAQs

Production quality, tone, and stereo image. The song itself stays the same, so lyrics, structure, and arrangement are kept. The clip is re-rendered through the Suno remaster model.
A pair of remastered clips in clips, in the same shape as Suno music generation. You get two versions to compare, and each has its own clip ID for export or further edits.
Five, each from 0 to 1. freedom sets creative freedom, tone sets tonal balance, strength sets how hard the remaster pushes, stereo_width sets the width of the stereo image, and clarity sets clarity.
No. Only clip_id is required. Any slider you leave out keeps the Suno default for it, so you can change one setting, such as clarity, and leave the rest alone.
Yes. Pass tags with style words such as "warm, analog, wide". Use it lightly if you want the remaster to stay close to the original sound.
