    Inverting Audio Channels in the Teensy audio boards

    Hi All

    I'm looking for to find how I can invert the phase in one channel in the Audio System Design Tool.
    I need to sum both channels with one of them inverted.
    Someone could help me?

    Regards

    Daniel Alayon

    Use a mixer, and in setup() set the gain to -1 on the channel with your signal.
