Hi Everyone,
Does anyone know if there's a standard way to calculate pan laws for
stereo-wide panning ?
By stereo-wide I mean panning something beyond the speakers by using
180-degree shifted signal in the opposite speaker. For example, for
beyond hard left you would output full gain signal
My thoughts exactly :)
Thanks.

Hello everyone,
Just putting this out there in case anyone has some suggestions. We are
currently looking at a multichannel panning method for 3D audio, we have
found a paper that describes the Speaker-Placement Correction Amplitude
Panning (SPCAP) method which seems to be an improvement over
L = ((1+w)L + (1-w)R)/2
R = ((1+w)R + (1-w)L)/2
0=w=2
0 = mono
1 = normal
2 = full wide

Beyond needs to be defined. It may be worth remembering that the
mostly standard pan law is predicated on the virtual source passing
along an arc of a circle centred on the listener (constant power), so
going beyond has to be defined in that context - the motion between
the speakers with
There is no valid psychoacoustic method to accomplish this and so there can

optical illusion and is quite restricted. The only reason that one can on

@Ross, Nigel: Thanks for information. That was enlightening. :)
I'd be really grateful if someone would suggest a book audio filter
design where I can see all of these comparisons in form of
mathematical equations ?

Unless I am completely mixing this up with some other system, I recall
some demo soundfile you posted some while back (must have been via
sursound) using two adjacent speakers, and getting a
quasi-surround/widening effect. I recall it particularly, because just

That was mine. There are several demo tracks on the Ambiophonic website
that you can download. But you should get the free Apple/Android(not free)
Ambiophonic app or the free Hotto Transcoder and play your own favorite
recordings via good speakers. Angelo Farina and others on the Sursound list
To me the (really) old invert a channel trick has never been a proper way
to get surround, while I'd avoid it because it's totally not mono-friendly
(obviously), I like the idea of enhancing a panning knob with it, as to me
it's always useful to have a section (in a sequencer or synth) that's
test.

Thanks for the responses,
Seems like I may have asked the wrong question.

In this instance I'm not really concerned with psychoacoustics. What I
