Yes, that is making more sense. All this business about un-baking the cake is new to me. I did know about Spleeter and derivatives, but I didn't think they had progressed so far.
Although technically impressive, I put this usage of AI in the same category as a gimmick or low-brow entertainment.
So what if someone painstakingly copied a Sinatra sound, reproduced his voice and changed the lyrics for a single song. The real "gold" is for an application to seamlessly do this for
any song with the user having full edit control of the output; and my prediction is that some company will provide exactly this within 5 years.
BiaB and AI could be a perfect marriage to allow the creation of fully editable custom styles and chord sheets (much like we have today) based on giving it a target audio sample. So if you want a Sinatra style, feed it a Sinatra audio sample. If you want a Frank Zappa, Chicago, chanting Monks meditation music or any other style, just supply the appropriate audio sample and the output would be a ready-to use SGU file. The days of scrolling thru and auditioning hundreds of pre-programmed styles would be replaced with laser focussing on
the style you want.
This technology needs to move from the novelty/consumer/listener domain to the creative/editable/musician domain.
