I am probably confused with the values for pahse offset. From what I understand, based on the docs, it looks like it should be the offset of the sine wave in degress. So the expectation is that 180 degree offset sine should cause a muted sound when added to a 0 degree offset sine. This does not happen, and even more so any adjustment from 0-360 to the phase does not do anything.
Creating a basic delay using the the time for a single cycle (.5/440) at 440Hz and adding to a non-delayed waveform gives the expected cancellation of sound. Also tried the mixer simply out of curiosity and as expected no difference for either phase offset or delay cases.
What am I missing? Any help is appreciated. Thanks!
