I2S
I2S is the a protocol for streaming and seems like the best way to sample audio input.
- Instructables example code: Does this code handle multiple reads? How do we know when a buffer is full and it's time to re-read it?
- i2s full tutorial:does not address reading multiple times from analog input
- Arduino library that seems to do magic but documentation for analog read and multiple buffers seems scant
- I didn't review this one but it might be worth a look
- Code from Google's AI bard that uses interrupts to know when the buffer is full. This is untested code.
