- Description
- Audio file saved in the AC-3 (Dolby Digital) audio format; can include up to six channels of audio (DD 5.1 surround sound with subwoofer output); uses lossy compression and often used as the format for DVDs, cinema theaters, and game consoles.
- Compressed audio file similar to an .MP3 file, but offers several performance improvements; examples include a higher coding efficiency for both stationary and transient signals, a simpler filterbank, and better handling of frequencies above 16 kHz; maintains quality nearly indistinguishable from the original audio source.
