Hi, I'm recording bird sounds on a Hi-MD mzh700. I was wondering-- where should I store my recordings? They are about an hour long, and I've been putting them in .wav format after importing through Sonicstage. Since the file sizes are often near 1 GB or so (an hour long in the best quality recording), I don't want to clog up my computer hard drive (only 40 GB). Also, I want to reuse the 1 GB minidiscs so I don't have to go buy more of them (almost 6 bucks a piece!). Any suggestions? Should I buy 3-4 GB DVD RW's and store them there? Or is there a way to compress and/or convert the .wav format for storage purposes, and then convert back to .wav should I ever want to listen to them again? I am afraid if I store the files in like LP2 stereo format that the sound quality will be messed up if I convert to .wav down the road. Thanks for any ideas.
