Greetings,

I am new to FMOD and am just now–literally–beginning to read through the API documentation.

However, the multi-card feature caught my attention.

I was wondering ahead of time if it would be possible to set up two sound cards in a PC with, say, two sets of four surround sound speakers.

Then, with one set near the floor and one set near over-head, be able to position a 3D sound within that space using FMOD?

Thanks!

Basically it’s very easy to do for you when fmod supports outputting on two devices at the same time with the same, low latency.

i think that it would cause problems when you have latency-difference > 20 milliseconds (just a guess) between the devices.

But if you ahve a correct output, basically, you could just calculate how much
the sound is over the camera, or how much lower, and then adjust the volume to that. surely only if both put the same signal out 😉

a very interesting idea…

regards

You could also get a single sound card with 7.1 output, wire your speakers up, and then add replace FMOD’s mixing DSP with your own that does basically the same thing, but sends the audio data to the speakers based on however you wried them up. Basically, just because a given surround channel is called center left doesn’t mean that it has to be use that way.

I think the spatializing would break, if system->set3dspeakerposition took a vector instead of xy, it could work :)

Yeah, good point. I was thinking that could be done in the DSP, but I was obviously not thinking clearly :)
