Inverting Audio Channels in the Teensy audio boards

[d_alayon]

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

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