I have just recently started recording. I am using a Fostex vr160 (I think that's the model number) that I just bought new. It's the 16 track digital recorder. I want to learn more about an external compressor, because my band's tracks sound pretty good after EQ'ing, but they just seem to "take up too much space", or maybe too much bandwidth. I'm not even sure what that really means, but I know I have heard better results that are more defined. Anyway, I have been told that a compressor before the recorder would help tighten the tracks up some. Can anybody tell me a little more about this? Any suggestions about how to buy one, what model, or how much they are? I really am trying to teach myself how to record great sounding tracks. I have a little bit of background in sound, as I spent 6 years in the military in signals intelligence, listening to signals through headphones, and I have a basic understanding of how sound waves work together. So, any suggestions or advice?
