Realtek HD Audio Drivers is a tool that allows you to listen to audio in HD on your PC.
Make sure your audio is perfect
Drivers are generally lightweight software programs that communicate with your PC's operating system and other complimentary software in order to make a piece of hardware work.
In this instance, Realtek HD Audio Drivers communicate with the Windows Vista or 7 operating systems so you can listen to music from your speakers. They translate data into audio signals that allow speakers to play audio externally.
Manage your devices
Realtek HD Audio Drivers can be centrally managed from your Windows Device Manager. To access your Windows Vista or 7 Device Manager, click on the Start button that accesses the Start Menu. Type "device manager" into the Start Search box and press enter. That should initiate the Device Manager where you can access the Realtek HD Audio Drivers program.
Boring, but essential, software
Realtek HD Audio Drivers can be a little tricky to access and manage, but these drivers will allow you to listen to audio in HD.
