aubio VS AmpliPi

Aubio is a good library for working with audio and midi: https://aubio.org/

How does this compare to Aubio?

Beyond that you'll need pitch detection/pitch tracking. It's not the most difficult thing in the world but you need basic understanding of digital signal processing, and the math behind it. Otherwise I think this library can do the heavy lifting for you.

aubio looks like an option. It contains the console program aubiopitch with a “jack” option for live audio. HTH.

I dunno, that article is paywalled. ES-HyperNEAT uses what's referred to an an evolvable substrate, which is the internal architecture of the ANN being involved. This provides for arbitrary neuronal wiring which is interesting and a departure from conventional GPU-based training architectures based on layers. For classifying audio stuff typically spectrogram analysis with CNNs are used, to pick up on latent features from a visual perspective. Probably getting your audio sources into an appropriate format would be the challenging part of it. Maybe experiment with the output from Aubio to get it into a representable format that an ES-HyperNEAT ANN could consume.

Hey, glad that you like the idea. For the audio-analysis, I'm using aubio (https://aubio.org/), great library, once you managed to install it :D Was a bit tricky in my case.

Thanks again! Check us out later on when you are planning your basement room. If there is interest, we are considering selling individual AmpliPi boards for those who want to integrate different portions of AmpliPi into their own designs. We are also open to suggestions for future incarnations of AmpliPi (including more affordable versions.)

Lincoln here from MicroNova. Both of these are features we have talked about adding to AmpliPi. Feel free to make an issue on our GitHub!

Awesome! Feel free to put any feedback you have in our github issues or discussions. We would love to know what your future use case looks like.
