When recording music, you always think of a well-equipped studio. However, if your budget cannot allow you to afford it, any modern PC will be enough for some basic tasks of recording. If you think that professional audio software is complex and Windows standard tools are disappointing, you can always try MP3Recorder Studio.
It is a compact tool intended for recording MP3 and WAV sound from a microphone. The program also offers lots of handy features that many people will appreciate. For example, you can use it to capture the sound from the speakers, which allows you to record the movie soundtrack that you are watching or a protected WMA that cannot be copied normally. It has a tool for editing ID3 tags of your files. In addition, you can configure this program so that it starts to record as soon as a sound is detected. For further information, I invite you to download the shareware version.
