An audio codec is basically a program that codes or decodes a digital data stream into audio output. The AC’97 Audio Codec is one of the most popular stereo audio codec software that users can download for free. The software can be used on most Windows based operating systems including Windows XP, Vista, Windows 7 and Windows 8. Unfortunately, the program is still incompatible with the Mac OS X operating system.

It comes in different versions with 2-channel, 6-channel, or 8-channel designs. The program incorporates converter technology capable of achieving a signal-to-noise ratio of over 90dB. Another great feature of the software is the fact it supports multiple codec extensions each coming with variable sampling rates as well as built-in high performance 3D sound effects.
