AC3 Audio File

AC3, also known as Dolby Digital, is an audio compression format developed by Dolby Laboratories for surround sound. Introduced in 1991, AC3 uses perceptual coding techniques to reduce the size of digital audio streams. AC3 is able to support up to six channels of audio - traditional left, center, right, left surround, right surround, and low-frequency effects (the 0.1 subwoofer channel). The format optimizes the audio bandwidth to deliver an immersive, theater-like listening experience. AC3 is used for many DVD, Blu-ray, and streaming media soundtracks. It can also carry descriptive audio for visually impaired audiences. The AC3 format led to more widespread consumer access to surround sound systems. Files using AC3 audio encoding are typically identified by a .ac3 file extension. AC3 remains widely supported despite the emergence of newer formats like Dolby TrueHD. It enabled greater audio quality and immersion compared to older stereo standards.
