How Can I Have More Than One Recording Device?

[doxiMAN_MAN]

Is that possible? I want to have more than one recording device in audition, I want to have a mix between a couple of channels, that all of them will go to the same one.

Can I do that? Or will I just have to download Adobe Audition 1.5 just for that?

Only if you buy an external multichannel USB audio interface. However you can, of course, record two separate mono channels just with the basic normal stereo sound card. There are various restrictions on using multiple separate audio devices in, I presume, Windows. Firstly all digital audio channel need to have synchronised sample rates. This isn't possible with separate stereo audio interfaces, except some very special expensive ones that will allow you to synchronise separate hardware together. Secondly ASIO audio drivers, which Audition prefers since they completely bypass the operating system, only allow one device to be used at any one time for both input and output. This is built into the driver specification.

How many channels do you want to record at one time. And will they be microphones or just line level inputs. Four inputs USB interfaces needn't be terribly expensive.

You can sort-of do this with ASIO4ALL, but the price you will pay is increased latency. Generally it's not a good idea, as ryclark hints. Technically, ASIO4ALL gets around the lack of sync by re-clocking everything, but this will inevitably reduce the quality of whatever you record. Getting the correct interface for what you want to achieve is by far and away the best way to proceed.

Here is what I did:

I've created 2 virtual lines with the software "Virtual Audio Cable", and set one of the lines as a microphone through Audition (to decrease background noises), and set the microphone to Line 1.

And then I set the "VLC Media Player" (what I wanted to do in the end)'s output to Line 2, and then I used the MME audio repeaters of Virtual Audio Cable to repeat Line 2 intro my headphones, and another one to repeat Line 2 into Line 1, which is my microphone.

Yes that will work in this case. But it is not quite the answer to your original question and, as you have found, is a bit of a pig to set up.
