Keeping up to date with the latest audio drivers is a must for all PC-using audiophiles. Your computer's sound card processes sound information for the PC and sends it to other audio devices such as headphones, microphones, and speakers, connected to the machine. Just like other hardware devices, a sound card needs a driver to provide a software component to the device, and this is where audio driver downloads step in. Here on FileHippo we list Realtek Audio Drivers. Realtek HD Audio Drivers allow you to listen to audio in HD on your PC, while Realtek AC'97 Driver provides drivers and codecs for its series of audio chipsets for motherboards.
