Simply install this software, turn it on and then all sound played on or through the PC will be recorded as wav or mp3 files. All audio is 'tapped' by a virtual driver directly within the kernel so the process is perfect digital quality. Records a direct digital copy of any audio played on your PC with no loss of quality. Saves files in wav  format with a wide range of selected codec and compression options. You can select to either listen while you record streaming audio or save audio silently.
