How online mastering works

You send the final mix as a high-resolution WAV file. I check it carefully in the studio, master it through proper full-range monitoring, then send you an approval master. Once approved, I supply the final masters in the formats you need for release.

What you receive

Streaming-ready WAV masters, CD-quality masters, vinyl-ready masters where appropriate, and DDP files if required.

Curtis also masters for Dolby Atmos, 5.1 surround, stereo high-resolution, CD and vinyl. Recent work includes the 2026 YES album Aurora, mastered at Curtis Schwartz Studio for Dolby Atmos, 5.1 surround, stereo high-resolution, CD and vinyl, with Blu-ray authoring also handled in-house.

Stereo, Dolby Atmos and surround mastering

Online mastering can be supplied for stereo releases, Dolby Atmos music, 5.1 surround, CD, vinyl and Blu-ray projects. Each format is prepared with the same musical judgement and attention to translation, dynamics and release quality.

The aim is not simply loudness, but translation, tone, dynamics and musical impact across every release format.

Mastering with release experience

Curtis has mastered, recorded, mixed and co-produced Stacey Kent albums with a combined total of over one billion streams. His wider mastering, mixing and production work includes projects for YES, Cutting Crew, Riopy, Emma Rawicz, Bee Gees, Colosseum and many more.
