for creators
It measures your mix, applies bounded tonal and dynamics processing, and validates the delivered audio. Intensity, tone, loudness, and stereo width stay in your hands. The service is in beta; your ears remain the final judge.
WAV, AIFF, FLAC, MP3, and AAC/M4A. Upload a mono or stereo file up to 15 minutes and 500 MB. For the best starting point, use a lossless export of your final mix.
The beta allows 20 successful masters per rolling 24 hours, with no weekly cap. Guests can master one distinct source track, including revisions. Each successful new revision counts toward the daily allowance; downloads do not.
Yes. Change intensity, tone, loudness, stereo width, or the optional genre hint, then render a new revision. Your current version stays available to play while the next version is processing.
After is a preview of the validated master. Before has a separate presentation effect: a mild muddy EQ, reduced high frequencies, and about 1.5 dB of attenuation. The original upload and its measurements stay unchanged. Download and compare the original for an untreated reference.
Tracks are stored in private storage and playback uses temporary links issued only after ownership checks. Guest audio is retained for 24 hours. You can delete a track and its audio from your recent work.
Validated masters are available as 24-bit WAV and FLAC. The listening previews are smaller files for playback; your full-quality downloads come from the actual delivered master.
You can pause and resume an upload. If your connection drops, choose the same file to resume it. Processing status comes from the server, and unsuccessful or cancelled jobs do not consume a successful-master allowance.
