Interesting, alas I missed that date.<br>
Something like that was in the back of my mind as a project (on my<br>
toilet paper roll TODO list ...)<br>
after being introduced to a "speech extractor" product by a HAM radio<br>
guy with hearing difficulties,<br>
which tracked harmonic envelopes to sort out what's speech and what isn't,<br>
so I thought, how about separating several speech profiles, and other<br>
noise sources, by determining coherent FFT frequency bin envelopes,<br>
probably could use smaller neural nets for that, which is "how the cool<br>
kids do things these days".<br>
I imagine that separating several speakers from blanket "noise", and<br>
perhaps each other, to be easier than different types of noise, music<br>
etc - but for me, the latter wouldn't be that interesting, so far.<br>
<br>
The inspiration came from trying to listen to interviews being given,<br>
with some protesting going on in the background, the noise floor of<br>
which made listening difficult, unpleasant or both, and it would seem<br>
nice if you just had a bunch of sources with checkboxes presented, and<br>
could uncheck the background noise ones.<br>
As it goes with something like that, it could be used for nefarious<br>
purposes also.<br>
<br>
Does that guy have some demo of a working program available?<br>
