Surround with ESS ? Multiple concurrent FFT ?
Mar 21st, 2007, 12:47am  
I’m looking for advices on how to do 5.1 surround sound (6 channels) with ESS.

If I load sound in buffers made from OpenAL, in order to be able to place sound sources in space, would it be possible to feed ESS directly with those buffers ?
I want to be able to do FFT on each of the different sound sources, therefore I can not “feed” ESS with the sound what is coming out of my sound card. And I’m trying to avoid to do everything in OpenAL.

Would it be even possible to run multiple FFT at the same time ?

[all this to add to my post in that thread : http://processing.org/discourse/yabb_beta/YaBB.cgi?board=Sound;action=display;num=1164147978]

ESS can only do stereo I think, no matter where you put stuff together, ESS only has left and right channels.

I think you can do multiple sepeerate FFTs in ESS however, since you can tie an FFT to a Channel when you calculate the FFT each frame.

yes... it's why I was looking to see if I could use ESS for the FFT and do the multi channel [6] aspect with OpenAL.

I right now looking at OpenAL to see how I can use it in my project.
