And it's opensource, though many of the inputs are licensed.
The code is at https://stromberg.dnsalias.org/~strombrg/music-pipeline/ (
https://stromberg.dnsalias.org/svn/music-pipeline/trunk/)
It appears to be more than 10x slower.
I haven't profiled it yet. I believe it's probably the "Blocklisting
files..." part that's slow. That part is O(n*m), and seems to take
forever. It's heavy on regular expressions.
Are regular expressions expected to be slow on Pypy3?
Thanks.
