Hear your next master.

Sunset Studio is a browser mastering tool: add a track on any device, choose a loudness target, and compare the result in a free 30-second audition. The page loads in your browser, then your audio is decoded, processed and played back on your own device. The separate Sunset Mac app exports the full-length, dithered 24-bit WAV.

Gentle aims for −14 LUFS, Balanced for −11 LUFS and Loud for −8.5 LUFS, all under a −1 dB ceiling, and Balanced is the default; the chain re-renders up to five times to land near your pick. The Mac app’s settings differ: Gentle −13, Balanced −10.5, Loud −8.5 and Max −7 LUFS.

No. The two versions aren’t level-matched in the Studio, so listen for tone and punch, not just volume. Switch between them while the Studio shows loudness before and after, plus the peak. In Sunset for Mac, equal-loudness A/B measures both versions and turns the louder one down.

Sunset Studio’s file picker, mastering controls, transport buttons and processing status are keyboard operable and labeled. Waveform canvases are supplemental to text loudness, peak and status readouts. Accessibility is an ongoing engineering target, not a claim that every use case is barrier-free, so report anything that blocks you through Sunset support with your browser version.
