I'm very new to the world of audio recording. I've done some basic voice recordings using some decent usb mics and Adobe Soundbooth 4 as well as Acid Studio 8. However I have a new project idea to capture a voice recording in an open space (hall, church, etc). I want to try to capture both the voice and the echo in two separate "layers" is that possible? or is it best to capture the voice recording then apply filters and such? I did like the idea of trying to capture an authentic echo un processed by a computer. I'm also looking for the type of equipment that I would need to get this all done. I'm on a budget (who isn't) but want to get a good quality recording. Is it best to use computers and usb mics? portable dat recorders? any words of advice would be welcome. Thanks in advance.
