Hi WMXZ,
How do I connect the digital mic to the teensy board? I tried your code but i'm not receiving any input from it. Thanks.

Hi WMXZ,

standard PJRC connection for I2S:
CLK to pin 9 (TX_BCLK)
WS to pin 23 (TX_FS)
SD to pin 13 (RXD0)
L/R to GND
3.3 to 3.3
GVD to GND
Can it be used for multiple(four) i2s input? How can I do something similar but with four i2s input?The one I posted is for digital (i.e. I2S) microphones.
Standard I2S allows two word-wise interleaved audio data channels. The distinction is made with the L/R pin. Thus, for 4 channels, you'd need a Teensy with 2 H/W I2S ports.
