Dolby Digital Plus

Dolby Digital Plus is a surround audio codec developed by Dolby Laboratories. It is an extension of the Dolby Digital (AC-3) codec, which is a digital audio encoding standard for playback on televisions, home theater systems, and other devices.

Dolby Digital Plus is designed to deliver better audio quality and more flexible audio encoding than Dolby Digital. It supports higher bitrates and a greater number of audio channels, enabling a more detailed and immersive surround sound experience. Dolby Digital Plus is used in many modern home theater systems, televisions, and streaming services, and is also included in the Blu-ray Disc specification.
