I'm a classical composer and I'm putting together my own recording setup to archive my own works. The recordings do not need to be "professional level" -- this is for my own personal portfolio, not for any kind of wide distribution. I don't have a ton of money to budget, I was thinking maybe $300-400USD total for 2 mics that I could use for simple stereo recording. I've been having trouble finding ANY info on this online with simple google searches. Most websites seem to focus on recording rock/pop music, which I have no interest in, or seem to be hawking much more expensive units. A friend recommended Shure SM57 but she has only recorded rock/pop, not classical. I am mainly looking at recording small chamber ensembles, say 1-8 classical players (any/all instruments), in small-to-medium recital halls. I don't need a "versatile" mic as I'm not anticipating using them for any other types of recording. I just need something that will record the live/natural sound of the room fairly well. I don't know a whole lot about microphones and I would appreciate any input you'd have! Thanks.
