I've been using the program Replay Music to record audio streams of my favorite show from real player and save them to mp3. It almost works perfectly, except for one thing: the lowest bitrate it can save the files as is 128kbps. For limited space reasons, I need the mp3 files to be 48kbps. I know that I can use another program to convert the bitrate afterwards, but that makes twice the work for me.
So, what I'm looking for is a program that can save real player audio streams to mp3 and can specify the bitrate at 48kbps. Any suggestions?
