From the long list of answers, I see lots of
speculation about Mr.
Shirkey's question. Some time back he approached me on the work that had
been done a very long time ago on phase-modulation to achieve panning.
He never replied to my subsequent information or queries.
Sorry about that. Been a little hectic the past few months.
I suspect that
this question is really all about the phase of the signal being
transported through any given audio driver, ALSA, JACK or whatever, so
the analysis is somewhat germane.
I think that a phase demod analyzer might be his attempt to solve his
real problem. I speculate that Patrick didn't actually ask his real
question.
I'm not sure that I can provide all the information at this stage
anyway... :-)
So, perhaps any Haas-effect plugin would satisfy
Patrick's needs.
Other than that, I'd make a really cool spectrum analyzer that ran the
Fourier analysis on two channels, correlated their phases then made a
+/- line vs. frequency for all to see so that the phase of the
components of the spectrum could be watched for phase relationships.
Suggestions?
That would be a useful tool.

Hi,
Can anyone point me to a simple code example for how to determine the
phase at a specific time in a waveform?
ex. if I have a sample that is 5 seconds long and want to know the phase
at 2.5 seconds
I'm open to code in any language or a scripted example if such a tool
exists. If there is an ui which has that feature I am also interested.
Cheers
