I’m about to start a small project and now want to find out whether it’s possible to do what I need with vvvv before I run into trouble.
In detail, I need to control the volume of 4 different audio files and send the 4 signals out via an external sound card (Edirol FireWire FA-101).
Can vvvv control/send 4 Audio signals at the same time?
Seems to work in general, but I’m experiencing a problem:
I have two FileStreams open, each streaming a different .WMA file. Each of the FileStreams is connected to one AudioOut. At the two AudioOuts, I have selected Edirol FA-101 Out 1 and Edirol FA-101 Out 2 as drivers.
My external Edirol FA-101 Soundcard is connected to two loudspeakers. Mono Out 1 to the right speaker, and Mono Out 2 to the left speaker.
Now the problem: no matter what I did so far, I was only able to get sound coming out of the right speaker. I switched the Outs for the two FileStreams to check whether both files work properly - they do. The stream connected to Out 1 is the one that plays out of my right speaker…
I also recognized that the control light at the soundcard is only flashing when I connect a stream to Out 1, not when I choose another of the 10 outputs of the soundcard.
Could there be a problem concerning mono/stereo? My loaded files both are stereo and I each stream them to a mono ouput - can I make the stream mono already in vvvv?
Would it be better to move the thread to the hardware section of the forum or can it stay here as well?
everyoneishappy – I think you are absolutely right concerning the Out/Channel behavior. Totally makes sense.
Using pan only turns down or off the left or right channel, do I understand this correctly? I would rather need a true stereo to mono conversion than loosing one channel. But if that’s not possible in vvvv, I’ll simply convert my files before loading them.
