Multiple audio outputs in .Net

Question

I am looking to build a PC box that can play up to 16 audio files(mp3/wav) out to 16 analog devices(think of it as 16 sets of speakers). There will be a one to one relationship for audio file to analog output. The solution that is being presented to be hardware wise is to use multiple sound cards, so my question is, is there a library available that will let me play an audio file to a specific sound card / channel?

Answer 1

Yes, the BASS library can do this. http://www.un4seen.com

C# wrappers are also available, a commercial one:
Bass.NET
and an excellent alternative open source C# wrapper for Bass:

Answer 2

I found this one while I was looking as well. http://www.alvas.net/alvas.audio.aspx

Answer 3

FMOD should do what you're looking for. It's also an extremely fast, solid and popular library overall.
