hi,
I'm having a bit of trouble finding a solution to my problem, wondered if you could help.
What I'd like to do is stream 16 mono audio channels to my users computers. They can plug normal headphones into their computer headphone jack and listen via a udp stream (think webcam but audio only).
Now i've got the client and server software sorted out. But i need to get those 16 audio mono channels into the server so they can be streamed. Some i can grab off the internet as a stream already and rebroadcast (commercial radio). But mostly they are none commercial sources.
The solution must meet these considerations:
So off i went to google to find a multi input sound card. It was surprisingly hard. I went to a few DJ stores and asked for their help, it seems my options are:
2 X M-Audio Delta 1010LT 10 Input cards (not a bad price and seems the simplest solution)
8 X horrifically cheap usb sound dongles (split the stereo line input into two, giving 16 channels)
High end commercial recorders. I've found some which i can't name here, used for telephone intercepts, but they are $12K per channel. And i don't need recording.
The other concern (especially with the m-audio card) is that the inputs have to present themselves to the computers sound interface (active-x to be specific) as a line input. They can't be only compatible with cakewalk pro or whatever
The other tip i heard is that some old soundblaster live cards, the ports on them are ALL dacs. Meaning i can convert the line out, headphone out, subwoofer out etc into line inputs. This is the the project that talks about that:

So questions to you (you wonderful people for reading this far)
Any other solutions come to mind?
Anyone else tried to do the same as me?

The solution must meet these considerations:
- 16-20 Mono channels via RCA Line-Level inputs
- all channels can be balanced prior to server
- all channels are mono or downmixed
- quality is not a concern as they are already "fm" quality 16khz sampling is more than enough
- low latency as some channels will be audio for matching video on video wall
- pausing or recording is not required
- users will listen to more than one channel at once, but must also be able to isolate (i.e no mixing the channels together before streaming)
