Process

How it works

Osmuse mastering is 100% online. As soon as you upload, your files reach us instantly and you get an email confirmation. Our engineers then master your tracks at the studio in Paris with human decisions: real hardware like the WesAudio ngComp and the Bettermaker Bus Compressor, for genuine transistor harmonics, alongside cutting-edge software for precision, then you receive your finished master, wherever you are.

Frequently asked questions

How do I get my music mastered online?

Upload your track as a WAV or AIFF file to Osmuse: the file reaches us instantly and is mastered by hand at the Paris studio, on a high-end hybrid processing chain (analog hardware WesAudio ngComp, Bettermaker Bus Compressor + cutting-edge software). You receive a listening link within 3 to 5 business days. The first track is free.

Is hand mastering better than automatic mastering?

For musicality and depth, yes: unlike cloud-based algorithmic auto-mastering services, Osmuse masters every track by hand on a hybrid chain combining real analog gear and cutting-edge software. You get an organic sound, with a color and dynamic an automated process cannot reproduce.

How much does online mastering cost at Osmuse?

Stereo mastering starts at €55 per track. Osmuse also lets you listen to a free excerpt for 4 days, with no credit card required, before approving the price and unlocking the full master.

How long does it take to receive my master?

Expect 3 to 5 business days after uploading your track. You receive a listening link by email to approve the result before the final files are delivered.

Which file formats should I send for mastering?

Send an uncompressed stereo mixdown as a WAV or AIFF file, ideally 24-bit, with a few dB of headroom and no limiter on the master bus.

Where is the Osmuse mastering studio located?

The studio is based in Paris. The service is fully online: artists worldwide can upload their tracks remotely and receive analog mastering processed at the studio.
