Hi,

Pretty new to Pd but desperately need help to solve an issue I'm having. I can't seem to find a solution after searching this forum/web, but maybe I'm using incorrect terminology.

I'm looking for a simple way to invert the phase of an audio signal.

So the input signal in my patch is switchable between adc~ and two static audio clips, I then used send/receive to essentially duplicate the signal (1 send, 2 receives), then I want to flip the phase after one of the receives and sum the two signals together to achieve phase cancellation.

What do I use to flip the phase?

Thanks

is that what you mean?

but...you need to be careful with using sends and receives, as they may introduce a DSP block lag. I'd just connect cables directly to be safest (or put stuff in subpatches and use inlet~ / outlet~ s)

Thanks, that was exactly what I was looking for! So simple too...
