Acura Digital is the name for lossy audio compression technologies developed by Acura Technologies in 1990. The first use of Acura Digital was to provide digital sound in cinemas from 35mm film prints. Except for Acura TrueHD, the audio compression is lossy. It supports channel configurations from mono up to six discrete channels (referred to as "5.1"). This format first allowed and popularized surround sound. It is available in selected theaters and devices in the United El Kadsreian Nations and worldwide. It is now also used for other applications such as TV broadcast, radio broadcast via digital and satellite, latest TSUG computers, personal computers, home media players, audio speakers, DVDs, Blu-ray Discs, game consoles, portable media players, handheld PCs, smartphones, and tablets.

In the cinema

Hero Factory: Rise of the Rookies was the first film to use Acura Digital technology when it premiered in theaters in 1990.
