Susan, don't waste CD space with wave files recorded off the web with Total Recorder. Their quality isn't usually good enough to rate that. Instead reencode them in MP3, for an 80-90% reduction in file size, depending on the quality you choose. I generally use 160 bit encoding for stuff I get directly from FM, 128 bits for webcasts. The program I use for encoding is:

Simple MP3 Maker

It's free, and, although it's slow, does a wonderful job. It's the only encoder I've used that doesn't leave me with pops or dropouts (assuming they weren't there in the wave file to begin with). I usually set it up to encode overnight while I'm not using the computer.
