About studio.audio
studio.audio is an online mastering service. It uses adaptive studio grade mastering, not generative AI. Upload a mix, compare the master with your original, and download a release ready master for streaming, distribution or CD.
Who it is for
Independent musicians, producers and mix engineers who care about how a release sounds and want masters that are consistent from track to track, without booking a studio session or being charged for a heavy subscription just to try a single.
What it does
studio.audio turns a finished stereo mix into a master with warmth, natural dynamics and professional loudness. Masters are true peak safe for streaming services and come as a DistroKid ready ZIP on Artist and Studio Pro. Studio Pro adds stem splitting, custom reference profiles and batch album upload so a whole record can be mastered with a consistent sound.
How it works
- Upload a finished stereo mix. WAV, AIFF or FLAC at 24 bit or higher is best.
- studio.audio detects the genre and feel of the track and runs one adaptive studio grade mastering process tuned to it.
- Every master is checked for distortion, with an automatic retry, and held to a true peak safe ceiling.
- Compare the master with your original using A/B playback, then download the formats your plan includes.
Loudness and true peak
studio.audio targets about minus 13 LUFS integrated. More dynamic material such as acoustic, jazz or classical can land between minus 14 and minus 16 LUFS. True peak is held at or below minus 1.0 dBTP on every master, and at or below minus 2.0 dBTP when the master is louder than minus 14 LUFS integrated. Full details are on the specs page, and upload tips are in the file prep guide.
