Are the portable sound proofing things worth the money to help sound quality of vocals? I'm worried because I know my voice will bounce off my walls and mess with the sound of the recording. Also wondering any good videos or advice on comping vocals and how to do it in Pro Tools LE 8. AND, when I've recorded before, as I'm recording there is a distinct delay from the mic to my headphones... Not sure how to fix this. I messed with the levels on my Mbox Mini to make that delay go away but then I couldn't hear the music in the headphones? Strange to me. If this sounds familiar than any info on this would be awesome. Thanks! Side note, I know specifications for Pro Tools but what are good things to look for in a computer that will run it smoothly? I'm looking at something simple right now. 4GB of RAM with a decent processor.
