PORT HARCOURT, NIGERIA, November 3, 2026. The InterSpace Group today announced a partnership with Masterchannel, the Oslo-based music mastering company, that brings professional mastering into the dashboard artists already use to release their music: both on InterSpace Distribution, the Group's direct-to-artist service, and on ToneGrid, its white-label distribution platform used by labels, distributors and music companies to run their own branded distribution businesses.
For ToneGrid partners, the integration means one more service they no longer have to build, source or send their artists elsewhere for. It ships at the platform level, so every label and distributor on ToneGrid can offer mastering to its own artists, inside its own branded dashboard, with no integration work on its side.
Artists open Mastering from their dashboard menu, upload a mix and get a mastered version back within minutes. Every master comes with a free full-length preview that can be compared against the original mix, with loudness-matched playback so the difference is easy to hear. Artists pay only if they choose to download the final master. There is no subscription, and nothing is ever charged automatically.
"A great release starts with a great master, and for too many independent artists that last step has meant expensive studio time or guesswork. With Masterchannel built into the dashboard, an artist can get a professional master in minutes, hear the whole track before paying anything, and release with confidence. Because it ships on ToneGrid as well, every label and distributor on our platform can now give the same tool to their own artists, under their own brand."
Eric Okechukwu, Founder & CEO, The InterSpace Group
Masterchannel was founded by a mastering engineer, an independent artist and a producer. Its technology combines human engineering expertise with modern audio technology: it analyses the sonic characteristics of an uploaded mix and calculates precise adjustments to tonality, dynamics and loudness. It does not generate or alter musical content, it was not trained on copyrighted recordings, and every master remains entirely the artist's own.
"Our partnership with InterSpace stems from a shared commitment to empowering independent artists. As musicians ourselves, we at Masterchannel understand the dedication required to produce great work, and we're proud to make high-quality sound accessible and affordable for all InterSpace's artists."
Christian Ringstad Schultz, CEO & Co-Founder, Masterchannel
