|I'm trying to find a cost efficient means of recording my band. I would like to have a minimum of 6 inputs/ tracks recording simultaneously.
My question pertains to this audio input device: http://www.griffintechnology.com/products/imic
-Can you plug a bunch of these (say 4 of them) into a USB hub and have the capabilities of a much more expensive stand alone multi track audio input device?
I found the following on another site. Does anyone have any idea if this would work? Sounds too good to be true.
In GarageBand, choose your new device from the input list and there you go! Theoretically, you can buy four iMics and an USB hub and you can have eight inputs -- but I don't know the maximum number of audio streams that can be used simultaneously over one USB channel. But, this is a lot cheaper than buying an eight-input device which can run up to $800. Enjoy!
To answer the question about USB and audio streams:
USB 1.1 (Or USB2.0 Full-Speed) should allow up to 6 channels of 48khz 24 bit audio, although that is using up the bus and if used often you may get drop-outs.
USB 2.0 High-Speed can get a lot more depending on the sampling rate and bit depth, but 16+ channels are possible. The same is true with Firewire 400, and of course more with Firewire 800.
