This second tool is one I've used for recording audio from the net into mp3 audio files. It is called Mp3 my Mp3.
This tool can be a little hard to set up, mostly because modern Windows operating systems hide the Stereo Mix setting, but there are instructions at the Mp3 my Mp3 site to enable this.
I've found this program very handy for recording songs, and it has some convenient options, such as silence detection, fine tuning sensitivity to silence between songs and starting a new recording as each song plays. You can also select the bitrate for your mp3 recordings, and adjust recording volume.
Mp3 my Mp3 will record anything that is being played through the computer system, so it is not just for online material. One disadvantage to the program is that it is limited to mp3 format in its output.
Be careful of the installer for Mp3 my Mp3, as there is one add-on that you have to avoid when installing the program. But that is becoming a common problem in free software.
