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,
if
L = M + S and R = M-S
is converting from L/R to M/S not as simple as
M = (L + R)/2 and S = (L-R)/2
or do simple math equations don't work here? (i have the intuition they should, but might very well be wrong)
greetings,
Kristof
