panning

kenichi's icon

hello,

how do you create a stereo panner that takes a stereo input?
examples with max only take mono input. (pan2, pan2S etc.)
also, nathan wolek's cppan and tap.pan are only mono also.
i don't want to lose stereo image of file,
but i want to be able to pan it from left to right.
like in most sequencers (logic, DP) it is still possible to pan stereo files.
how do you do this in max?
i want to use a hslider to control left or right placement.

i know this has been discuss before, and i've looked at other postings, but no examples seem to work correctly, the stereo images seems to always be stronger on one side.

Thank you for your help!

stereo is just two mono signals. take it from there.

thanks. i'll give it a try.
so basically what you are suggesting is using two pan modules...one for each channel?

simplest way is instead of one mono signal going to both left and right, take the right to the right channel, the left to the left. adjust relative gain levels for panning effect
or you could experiment with using two panning modules, might sound interesting

that's one way. don't get too hung up on the idea of "panning" - it's
just a name.
you could solve this problem a lot of ways without a "pan knob" in
there. i've
done it using two sliders... or four.... or some other kind of
graphic interface.
i'm confused about one thing you said - you wanted to "pan without
losing the
stereo image" - i'd be interested to see how you work that out...
maybe in quad?

what i meant by this, bruce, is that at center position, i want my stereo file to have it's full stereo image. of course at hard left or right, it would be only coming through one side.

so, does this look right. aurally, it sounds right, but it doesn't really make logical sense to me. any successful examples would be very appreciated. i've been confused by this conceptually for sometime.

thanks,

I believe this is the standard way in stereo equipment. You could test
on a mixer with a stereo input channel, or even playing a CD where some
instruments seems to be panned hard right or left. I'm pretty sure that
panning hard right or left is the same as muting one of the stereo
channels. If you pan hard left, the right input channel doesn't get
mixed to the left speaker, you only hear the left input channel.

Best,
Trond

This is an abstraction of how I do it - it uses Nathan Wolek's cppan.
Be sure to look at the Get Info for each of the inlets and outlets to
see how to use it:

i was sure you meant it like that. :)

that can be done easily using 2 copies of 2pan - just
pan the right channel from the middle to the right only
and the left channel only from the left position to the
center.

As the actual gain part was missing, a modified version:
