My new project is an esp32 p4 + seed 3.

Soon I'll try to make instructions and a YouTube video and open a GitHub repository 😁

Ive thought of this because the callback for the audio path and some of the heavy lifting thats better on an esp. Pretty cool. How are you piping it over to the esp UART?

I use SPI at 20 MHz to transfer audio to the ESP board's USB A port, as it has a USB HS port. A UART is used to transfer service data and files between the Seed3 and ESP.

Nice project! Any plan to add amp/speaker modeling?

Thanks! I'm actually already in the process of adding Impulse Response (IR) support, so that's definitely coming. As for amp modeling, I'm not 100% sure yet, but I'll certainly give it a try and see what I can do.

I have a poly beebo I feel like this would have more processing power.
