Many tunatic users get confused about using it to identify music playing on the computer. Tunatic is normally configured to identify music through microphone. In many cases this degrades the music quality and sometimes tunatic fails to identify music. To configure tunatic to identify the music playing on the computer instead, the following steps may be followed.
Open windows volume control either through control panel or by double clicking the volume icon on the system tray.
Click on Options and then Properties.
Select the 'Stereo Mix' option by putting a check mark on the select checkbox below it.
