This is an interesting development, especially since they include the methodology they use in the study. I’m not good at programming, but it feels like it should be reasonably easy to program something that can do something similar to this methodology.
It might be a bit of a white whale, but I’d love to be able to pick out notes without needing a reference pitch.
Notably the study appears to only have been about single notes rather than chords and harmonies which people with absolute pitch can definitely identify, but I’ll take being able to identify single notes just fine.
