Realtek audio sound cards feature a graphic equalizer to adjust the sound on your computer to your taste. Because digital audio is now being compressed at different qualities, there is no set equalization that will be ideal for all files. That is why you have to be able to get into the Realtek equalizer to make the proper adjustments. Many Realtek sound card users have reported that their graphic equalizer has disappeared in Windows 7, but restoring it is simple.
