Just keep in mind that you're working with raw data and you want to maintain as much quality as possible. If you're working on a complete archive and would like to share it with the community, make sure you always save the data as Windows PCM. This is standard lossless .wav quality, which gives you no reduction in quality whatsoever.

Also, you can work your way through the entire stream piece by piece, creating new copies of each sample and working on them until you're content with the results. It's tedious and frustrating, but it's a solution. Feel free to ask for help at any time, if you're unsure about anything. It would be a shame to have you working on the entire stream and then realising something is wrong. I've done one too many rips over the past couple of years with the end result just being another run with the recording software... Not pretty.
