The Audio Research Group

Developed by software engineer James Clarke.

De-mix is a revolution in sound technology.

Developed by technical analyst James Clarke, the De-mix process opens up access to previously locked recordings, allowing audio engineers to craft new mixes and masters. Creating a superior listening experience for music fans, the De-mix process reinvigorates catalogue and breathes new life into forgotten tracks or bootlegs.

Using algorithms that are trained on target instruments, De-mix can extract these components to enhance or reduce targeted EQ or isolation. Not only can De-mix be used to adjust the levels of musical elements within a mix, it can also make vocal isolation or removal a reality. The new process unlocks mono recordings or those where full multi-tracks do not exist.
