Hello lists. Anybody working on Audio Descriptors with Csound? Opcodes, UDOs, Plugins, and even scores could be useful in my search.

Hi This is something I've been working with on-and-off for some time but is not really ready for public release yet... However within a few days I could pull together into a legible state and share some bits, but they would be in a very beta state, at the most. There are two approaches I've been using, mainly for concatenative resynthesis/similar: Using MFCC natively with the mfb Csound opcode. Hopefully could be of some interest!

I would be most interested in this too. What you do with LibXract sounds interesting. I've done some feature extraction too, for use in the crossadaptive processing, the analyzer module could easily be untangled and used in other contexts: all best Øyvind tor. 11. mar. 2021 kl. 22:49 skrev Richard Knight <richard@1bpm.net>:

Hi Thanks Øyvind, that's really interesting and I'll have a proper play shortly, I hadn't considered the possibility of such detailed feature extraction natively in Csound. My LibXtract opcodes are currently quite experimental - I need to refactor some bits, but they work to get some usable features into Csound. Happy to have any suggestions or help if any issues compiling etc. Have tested on Windows and Linux. Also related, here's my native Csound concatenative resynthesis demo, using the mfb opcode to extract/store/match MFCC analysis: all the best, On 2021-03-12 15:13, Oscar Pablo Di Liscia wrote:
