It’s also triggering a mass conversion of older stereo tracks into Apple’s Spatial Audio format, priming and preparing music catalogues for the future of audio listening. Wired wrote an article about this back in March. It’s also led to some more advanced tech developments like the ability to ‘upmix’ old music whose tapes have been lost, warped or degraded so they can’t be used. It’s a huge development and not only is it big news for DJs and producers looking for ways to get instant acapellas from their favourite tracks, or to sample just the drums without owning the parts.

Technological developments in recent years - largely based around AI and machine learning - have meant that it’s now possible for software to identify certain elements of a track and mute them, or solo them, sometimes in real-time. Some techniques - like phase reversing the instrumental with the vocal version - made it possible, but you had to have access to an instrumental and the results varied from track to track. Up until recently, it was near impossible to extract a vocal, for example, from a mixed track. Stems are the name given to individual parts of a song that make up the complete track, like drums, bassline, vocals, hi-hats, snare, synth pads, etc.

After being the holy grail for producers and DJs for decades, over the past few years, it’s become easier than ever to separate stems from a full, mixed down stereo track.
