    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.

    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?

    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.

    Do you mean something like using 2 audio adapters with a teensy 3.2 board? How do I connect each i2s input to the teensy board with 2 audio shields? (Sorry, I think I'm lost..)
