Hi all,

Is it possible and if so how can I invert the phase of an audio signal in
Csound? Thanks!

Ryan

Hi Ryan,

something like

asig = -asig

should do the job. A phase inversion is nothing more. Or did I misunderstand your question?

Yesss, some things are really easy in digital signal processing, 
compared to analog synthesis.
