Those sound really interesting as the 64bit core also has quite a good clock, dunno if I can beg, borrow or buy one as I am interested.
I haven't an absolute clue of what its capable of but looking its has possible use as a usb/wireless mic array and maybe with the npu a mic array usb/wireless KWS.
I have been looking for an alternative to the Esspressif Esp32-S3 because of thier tendency to provide hardware blobs than open source which is near all there audio and KWS models.
Doesn't matter if I can not grab one but interested how the devs are getting on and what its capable of.
https://github.com/sipeed/TinyMaix seems to support the NPU whilst audio there is some choice
It does seem to have mic in but when I see a ADC labelled as general purpose it tends me to think from experience that it may be noisy and I2s (which it is also very capable) might be the way to go.
I did a simple realtime delay/sum beamformer on the pi which is my normal code molestation/hack https://github.com/StuartIanNaylor/Proje...ee/main/ds
Also done a lot of work with a lot of KWS models and would be interested how and what the Devs are finding with the bl808
