Hi,

just want to say something here. I know VBAP can do surround. But my point is what is the best way to create more user friendly surround sound panel so that audience can easily understand sound panning?

thanks

Take a look at the Ambisonics Tools from Philippe Kocher:

VBAP may have been suggested because there is a lot to getting the
proportions/levels etc. to getting a nice spatialized sound. Here is a link
to a very nice library, which also has its own GUI, that will do all you ask
and much more. You can use an object like "hi" if you want to hook up a
joystick or something like that. Search this list if you have any more
questions, as there is a huge wealth of information about this stuff.

You can try holospat objects (panpot and multiouts~)

I created some wrappers around VBAP in the CNMAT Max/MSP/Jitter Depot. http://www.cnmat.berkeley.edu/mmjdepot/

I'd use a multislider for all 8 channels, or 16 if you go that route. Presets and pattr work well for this. The slider value list (probably 0 to 127) will set the real audio-control elements (gainfaders~) which can be hidden. You can also have a separate matrixctrl to turn the channels on and off. Don't use a gate~ as you'll get clicks, rather set gainfader~ volume to 0 then set to previous level -- like a mute. The interpolation time in the gainfader~ will prevent clicks, set it to somewhere between 10 and 50 ms, or longer if you want more fade time.

The trick is mapping the linear values of the sliders (or knobs or faders or whatever you use) to the right logarithmic values for the audio, I messed with this a lot and wound up using a table lookup. So, 128 values that map on a curve that sounds right. This was just for panning L and R, so this application will probably need a bit more fiddling...

VBAP doesn't do any bass management. You could do that yourself, and pan in a 7.0 setting, though.

Hi MZ,

Those objects are unbelievable!!!!!!!!!!!!!!!

Are you teaching Max/MSP? I want to be your student. I am serious. Please let me know how to apply or how to attend the class? I am in Colorado Denver right now but I will move to San Francisco next month.

thank you so much
