Does a WAV from Suno still need refinement?

Listen first. WAV preserves the audio it contains; exporting as WAV does not itself repair noise, harshness or missing detail. Enhanced can synthesize plausible high-frequency detail, but it also changes texture and timbre. Compare with the original and keep the result only if it helps. If the mix already sounds right, use standalone Finalize without restoration or cleanup.

Where do I choose the loudness target?

At final listening. Finalize starts at −9 LUFS, with −7, −11, −14 and −16 also available. Compare the sound and measured loudness rather than treating one number as right for every track. A target is a request: the rendered result may fall short, and the measured LUFS is shown with the version.

Can I come back to final listening later?

Yes. Close the window, then use Open final listening on the track to return. Generated previews are saved automatically. Unrendered control changes reset on close; any render already started continues. Confirm and close session when you have finished comparing: it keeps your main result and downloaded versions for 7 days and clears other previews and temporary working stems.

What format does Finalize download?

Mastered downloads are 24-bit WAV. Every new setup starts at 44.1 kHz, including Pro and Studio. Those plans can explicitly choose 48 kHz for a version at final listening; previous choices do not change the next setup's default. Check your distributor's delivery requirements before submitting a release.

How to master Suno tracks for release: a practical workflow

Published May 25, 2026 · Updated October 11, 2026

Mastering is the last opportunity to check a mix's tone, dynamics and delivery level. It does not make every track better automatically. Start with the version whose arrangement and performance you want to keep, then compare each processing choice with the original.

1. Choose the starting point

Upload MP3, WAV or FLAC, up to 8 minutes. If you use Suno, its download-format guide lists WAV for Pro and Premier subscribers on the web; mobile downloads default to MP3. Check the actual file rather than assuming its sample rate or bit depth from the plan name.

Choose Enhanced when you want neural restoration. It uses GPU processing to synthesize plausible high-frequency detail and costs 2 credits; the result can change texture and timbre. Optional AI artifact removal adds a cleanup stage for 1 extra credit. Flow Matching is temporarily unavailable; its Normal and High settings use different processing depths. See the preset comparison for the different approaches.

Enable Finalize with Enhanced on Hobby, Pro, Studio or an active welcome trial for 1 additional credit. If the uploaded mix already sounds right, choose standalone Finalize for 1 credit instead: it starts from your mix and skips restoration and cleanup.

2. Rebalance only if you need to

On Pro, Studio and active welcome trials, Enhanced with cleanup can use Advanced mode to pause at the stem mixer. Set bass, drums, other and vocals, choose the original vocal, process the full vocal, or separate lead and backing. Add reverb to any treatment; it starts at zero. Advanced mode starts off: enable it before each submission. Use Continue to Analogue Colour when the balance works.

Advanced mode is optional. With it off, a Finalize track still reaches Colour and final listening. The Advanced mode guide explains the vocal controls and temporary working stems.

3. Choose optional Analogue Colour

Audition a curated hardware capture on the accepted mix, or continue without colour. Level matching starts off and Volume starts at 0 dB. Raise Input Drive to bring out the device's character, and use Volume to compensate the level. Then dial in Delta amount and recheck Volume as needed.

Automatic Level matching is optional and bypasses manual Volume while on. During the session, each mode remembers its own Drive and Delta settings. The first matched audition starts with your current settings; switching matching off restores your manual Drive, Delta and Volume. Listening level is a separate playback control and does not change the saved audio. Volume compensates the captured device output before Delta is calculated. Delta at 0% keeps the source unchanged, 100% gives that adjusted device output, and 200% doubles its difference from dry.

Colour happens before mastering. Your saved processing description identifies the equipment used, such as SSL Fusion/SSL Bus.

4. Compare the final-listening preview

Use the A/B controls to compare with your original upload. One signal meter follows the active file before listening volume. Choose the reference here: a factory preset, saved reference or uploaded file. Set mastering strength and loudness, and change one control at a time.

Glue Compressor: inspired by classic British console bus compressors. Adjust the threshold in dBFS. Link makeup holds an estimated compensation gain; unlink to adjust gain yourself. Both compression and makeup bypass when Glue Compressor is off. The meter shows gain reduction.
Resonance Mix: blend from the untreated mix at 0% to resonance reduction at 100%. Instrument Humanizer is available earlier in Analogue Colour.
Stereo Air: optionally add high-frequency air to the stereo sides.
Stereo Width: narrow the whole track toward mono or widen it beyond its normal 100% width. This is saved in the render.
Mono check: temporarily listen to the entire track in mono. This listening aid is not exported.

Listening controls prepare when you open the preview. Once ready, adjust Glue Compressor and Stereo Width during playback without loading another preview. The original loads separately for A/B comparison, so you can listen to the processed preview while it loads.

5. Choose loudness by listening

Finalize offers −9 LUFS by default, with −7, −11, −14 and −16 alternatives. Compare punch, vocal clarity and distortion at similar listening levels. A louder setting is not automatically a better master. Check the measured LUFS of the rendered version; a requested target may not be reached.

Spotify's Normal playback setting uses −14 LUFS and can raise or lower playback gain within its headroom rules. Its mastering guidance recommends −14 LUFS and peaks below −1 dBTP, or below −2 dBTP for louder masters. These are Spotify's recommendations; The Refiner's −9 LUFS default is a product choice. Read the current Spotify loudness guidance and your distributor's requirements before delivery.

6. Render what you want to keep

The default preview uses no download slot. Choose Render & download to save a version with your selected settings. You have up to three distinct mastered versions at no additional credit cost. Repeat downloads are free and do not use another slot. The unmastered comparison also uses no slot.

Mastered downloads are 24-bit WAV. Every new setup starts at 44.1 kHz, including Pro and Studio. Select 48 kHz explicitly at final listening on those plans when you need it. A previous 48 kHz choice does not change the next setup's default. If you cancel the confirmation or need to sign in again before starting, the next setup returns to 44.1 kHz. Saved versions keep their recorded rate. Listen to the actual downloaded file before sending it to a distributor or mastering engineer.

When you have finished comparing, Confirm and close session keeps your main result and downloaded versions for 7 days and clears other previews and temporary working stems. Confirmation alone uses no slot. If the warning says you have unrendered changes, render them first if you want to keep that sound.

You can close the window and return using Open final listening on the track. Generated previews are saved; unrendered control changes reset on close and any render already started continues.
