Built for creators who close tabs
The upload request creates a job record; Python workers handle the heavy audio processing after the page is gone.
Upload
Send one mix or a ZIP/multi-file stem set for deeper control.
Queue
Jobs stay pending until workers accept them, so a busy site does not block page loads.
Master
Processing uses the current tone-safe chain: no low-end removal and no pitch drift on full masters.
Notify
Users get a site notification when the mastered track is ready to download.
Quality guards customers can trust
SunoMaster should sell confidence without delivering thin, lofi, or broken masters.
Bass stays intact
The old bass-thinning filter is not part of the current production chain.
Vocals are protected
Stem jobs run input and output quality guards before delivery.
Studio polish
Full Master uses light compression, conservative EQ, and a limiter ceiling around -1 dB.
Credit packages
Credits can be used across SunoMaster and other creator actions. Larger packages lower the per-credit cost.
Common questions
Yes. Once the job is created, the Python worker queue handles processing in the background. The results page and site notification show completion.
Stems give the processor more control over vocals, drums, bass, and instruments. Stem Clean and Full Master are better choices when a track needs more polish.
No. Distribution policies change. SunoMaster focuses on release-ready audio quality, clean metadata, and professional mastering. All sales are final.
The job is held as failed instead of being delivered as completed. That prevents paying customers from receiving a broken output.
