Breaking up is hard to do, sang Neil Sedaka, but stem separation services and plugins are fast becoming ubiquitous. Perhaps developers sense a gold rush before this kind of audio extraction becomes a feature that comes standard in every DAW; Apple recently added it via updates to Logic Pro for Mac and iPad, and we’d already seen it in the likes of FL Studio and Serato Studio.
