Your entire catalog, ready for Differential Mode. A similarity-steered algorithm derives the Differential Mode signal from recordings that were never captured with M.A. hardware – no new format, no remastering.
M.A. Extraction Algorithm
The algorithm continuously measures how similar a pair of channels is, moment to moment, and uses that to steer how much Differential Mode it derives from the channel difference. It is the bridge between the world's existing recordings and M.A. playback.
A normalized cross-correlation runs on any two channels of a stereo or multichannel program – L/R, or any pair within 5.1 / 7.1.
A push-pull generator produces the Differential Mode base from the difference of the two channels.
A similarity-controlled gain stage adapts the Differential Mode moment by moment as the music changes.
The original channels travel untouched, plus compact metadata – Differential Mode is rendered on the playback side. Streaming-friendly, fully backward compatible with every existing player.
Stereo and multichannel convert directly in DSP. Mono and historic recordings – which carry no channel difference to work from – are upconverted through a studio re-amp workflow: played back through M.A. systems and recaptured with Triple Microphone Units into immersive formats such as Atmos and 22.2.
