Hi. So, I know there is M-audio's MobilePre USB but that's the only one I know about. I'm thinking this won't be enough as far as noise/hissing goes. I'd like something better for clearer vocal recordings, so I can use compression a bit more liberally and tick all those sound engineers off. Something that I can also take with me (along with my laptop) when I feel like taking a trip and experimenting in the car, up in the mountains or in the airport parking lot where I feel more inspired. Not very professional workflow but whatever. Alternatively, is there a way to work around this? Make a conventional preamp work where there are no electricity sockets around ? I heard something like a Firepod would give a much clearer signal than MobilePre USB and even though it's more than double the price I'm be willing to pay if there is a way to use it in the car.
