What is a .ac3 file?
AC-3 (Dolby Digital) is a lossy multichannel audio codec designed for surround sound, supporting up to 5.1 channels. It is standard for DVDs, digital broadcast, and home-theater audio tracks. Raw AC-3 files carry the encoded surround bitstream directly.
How to use this file
Use an example AC-3 file to test surround-sound decoding, channel-layout handling, and media pipelines that demux or pass through Dolby Digital tracks.
