Realtek High Definition Audio Codec is a free audio software released by Realtek for use on PC devices. This package contains all the essential codecs that are needed for high-definition audio processing and output using various Realtek devices and chipsets.

The Realtek High Definition Audio Codec is the successor to the older AC'97 Audio Codec standard that it made for the previous generation of devices. It brings with it multi-streaming support, 7.1 surround sound, and it's capable of even higher audio sampling and bit rates.

What's included in it?

AC'97 is an audio codec standard developed by Intel in the late 1990s. It was used on the majority of motherboards, modems, and sound cards during that time. It featured 5.1 surround sound support and could process audio with up to a 96 kHz sampling rate at 20-bit resolution. However, as technological improvements to audio chipsets came, so did the need for a new standard. Enter the High Definition Audio Codec.

The Realtek High Definition Audio Codec essentially follows the same standard that Intel established. The only difference is that this particular package was specifically adapted for use with the company's range of chipsets and audio solutions. It features the same support for the latest 7.1 surround sound technologies, as well as the capability to process and output audio with up to 192 kHz sampling rates and up to 32-bit resolutions.

Another highlight feature is multi-stream support which lets you multiple audio streams to different devices at the same time. Now, before you go on and install this codec pack for yourself, just be aware that not all Realtek devices are supported. You can refer to its official web page for a full list of compatible chipsets to see if yours is included.

Essential codec pack for Realtek devices

If you own a PC desktop or laptop that uses an audio chipset made by Realtek, chances are, you already have this codec installed. If not, the Realtek High Definition Audio Codec is a must-download to ensure that you get the best audio playback possible for your computer. It has all the latest audio technologies included and installation is a simple process.
