You've come to the right place then! Everyone has been mentioning dynamic microphones. For acoustic guitar and voice I would go straight for a condenser to catch as much nuance as possible. If you have no mics at all, I'd recommend getting one dynamic and one condenser of comparable quality. Considering that you can get an interface with 8 inputs for the cost of an 8 channel mixer and a stereo interface...definitely not! I think it's much more practical to get an interface with all the inputs you need, record on seperate tracks and mix in the software. As previously suggestioned, the M-Audio Delta series sound cards are very well supported by Linux and have a wide range of options. Be wary of new Delta 1010 cards though, because they changed something about them in 2007 that messed up their compatibility. My website hosts a list of aaaaaaaaaaalmost all of the officially supported interfaces: http://www.linuxstudiopro.com You may also want to invest in studio monitors at some point. They are expensive, but much more accurate and unbiased than even the finest computer speakers. If you want to make good recordings and mixes you need to hear the music accurately. We could talk about recording and mixing environments as well...but you should just buy a good book on recording. Good Luck, Dirk! Roger -- Click to begin your health care training online.
