The New Era of Digital Audio

Dolby AC-4 is one of the latest technological advancements in the audio industry. This is a new audio format and delivery system that is designed to render any source type of audio, whether it is a stereo mix, a 5.1 or higher surround mix, or an object-based mix (think Dolby Atmos where a sound can be implemented anywhere within a three dimensional space), and optimize it to suit the playback device. This essentially means that any audio file will be rendered to playback through a smartphone with headphones just as well as it would a surround sound system or even the new Atmos system.
