I usually visit www.sharewarejunction.com and www.afterdawn.com, find some good recorder software, and try them. I feel "Record and Edit anything into Mp3" and "RIP Vinyl" are the ones that can do what they claim, but which one is better? Anybody knows? The above picture is from "Record and Edit anything into Mp3", the nether one is from "RIP Vinyl"
Oh, I forget to say one thing probably important to you: "Record and Edit anything into Mp3" can still split and join mp3 ogg file.
