Hi Ronnie,
you would need a Mid/Side recorded audio file, I'm sure the trick
doesn't work with normal stereo. But no I don't have a patch. Normal M/S
uses M and S instead of L and R. The S track gets panned left, and then
an identical version gets panned right and inverted in phase, in Pd this
would be [*~ -1]. Then use a samplewise delay on the M track, which is
panned center (i.e. [*~ 0.5] sent to both left and right after the
[z~]). To a point, the longer the delay in samples, the "higher" the Mid
track seems elevated.
There could be plugins to convert normal stereo to M/S. I recall seeing
such a thing in my Ardour plugins, so it probably came form one LADSPA lib.
Best!
Derek

Hi Derek this sounds very interesting, is there an example patch of
this trick to share?
thanks

I've created the psychoacoustic effect of azimuth with Mid-Side recordings
on stereo speakers before. Use traditional M/S panning: Mid = Center, L = +
Side, Right = - Side, and add a samplewise delay to the Mid channel to
"elevate" it in the sound field. I've never seen this trick discussed, but
then again I'm not reading a lot of academic literature either.

Hello, i was wondering if its possible to perceive azimuth with 2
speakers? Ive tried earplug but it just work with headphones, is it
possible to create azimuth with speakers? If yes is there any library
or object for this in pd?
