Osiris Studio is a Los Angeles-based mastering and audio restoration services facility owned by multiple GRAMMY® Award winning mastering engineer Michael Graves. We specialize in providing state-of-the-art audio restoration services to the entertainment and archival communities.

Audio that needs help. That’s the unifying theme to the types of projects that Osiris Studio specializes in. For projects that will be commercially released this may be a rare performance recorded to an old 78 rpm record, clouded by surface noise and years of neglect. In the archival world it might be long-gone voices recorded to deteriorating or obsolete media. 


All have one thing in common; the audio is there, it just needs someone to help bring it to the foreground and make it sound the best it possibly can.

Because of the nature of most of the projects we receive (rare, one-of-a-kind recordings, deteriorating media, etc.) our goal is to provide our clients with the highest quality product possible, because there may not be another opportunity to do so.

This is accomplished through years of experience, comprehensive knowledge of current and aging media types, using only the best possible playback equipment, employing uncompromising analog to digital converters and careful treatment of the audio; both analog and digital.
