I followed this tutorial on building a microphone with two MEMS mics and a cheap USB sound card - it works pretty well, although I'm looking to upgrade the MEMS mics to some with better SNR and sensitivity.
I was looking at these microphones. They output i2s data, whereas the MEMS mics in the tutorial output an analog signal (edit - not PDM data).
If I use one of the same cheap USB sound cards, is that capable of receiving i2s data in the same way as they are receiving PDM? I understand that these i2s mics expect to output sound to a "DSP, microcontroller, or codec" - I'm just not sure if the sound card is considered one of those.
I also am aware that i2s MEMS mics have pins for "word select" and clock -- are those connections required for an i2s microphone to output a signal?
