I'm 99% certain that the Knowles SPH0645 used on that Adafruit breakout will work with the driver & steps for the Invensys ICS43432 I described here: viewtopic.php?f=44&t=173640

That's not an I2S mic, which would allow you to connect it directly to the Pi's I2S port.

Instead, it has an analogue output, & as such needs an additonal ADC board between it and the Pi.

Yes i have seen that, but thats for the i2c mic that i don't have yet, i have the spw2430 microphone and it seem that i will require another board to connect with the pi. i am now considering getting the i2c that was mentioned but i would like to know which is better.
