I need to read multiple microphones (>=4) with a high sample rate (more is better.
The MAix BiT offers the following but I am open to buy another board, preferable a RISC-V.
APU (Audio Processor) inside, support 8mics, up to 192KHz sample rate, hardcore FFT unit inside, easy to make a Mic Array (MAIX offer it too)
- How do I connect the 8 mics?
- Can I only use I2S mics which already did the AD sampling?
- How can I use the connected mics on another device, preferable as USB-Audio like other devices handle it?
