Interesting. Would that involve reading from `/dev/snd/pcmXXX`, or some other approach?

Thanks, I'll study that example!

I have some questions about the tradeoffs for different ways of reading from an ADC via SPI. The problem I'm trying to solve is detecting (and timestamping) a fairly short (<1ms) spike in the strength of a signal. The frequency domain is about 1-4kHz, so sampling at about 10ksps should do.
