Is there an easy way to invert the phase of an audio signal?

Awesome, thanks!

Could you elaborate a little bit on how that works? I had no idea there was a way to invert phase. And if you can invert phase can you control the entire range of the phase using this? Say I wanted to offset the phase of 2 signals by 45deg or 90deg?

The factor simply multiplies the signal by a constant value. Multiplying by -1 will effectively invert it, which is equivalent to inverting its phase. I don't think that this method can offset the phase of your signal, because offsetting implies introducing a delay, which is beyond the scope of this simple device. If you want to apply a phase offset to a stereo pair, you could use the StereoDetune and use its Delay control.

turn one factor to -1 and it completely converts mid signal to side signal. do i recommend it? no.
