AUDIO FORMATS

There are various formats that audio may be presented for home theaters. These formats will be
briefly discussed in chronological, as well as, technological order. The most basic audio format is
monaural (or mono) sound, which consists of a single audio channel. Mono sound can be presented
with a single speaker (old TV, cassette tape player, simple radio, etc) or with two speakers producing
identical sounds. The next advancement of sound technology came in the form of stereophonic (or
stereo) sound, which consists of two audio channels. Stereo sound was the first format to give depth
to audio by providing both left and right sound fields.
The advent of surround sound began with the deployment of Dolby Pro Logic. The Dolby Pro Logic
format creates multi-channel surround sound by matrixing a center channel from the left and right
stereo signal. The same 2ch stereo is also matrixed into a single mono surround channel, which is
often reproduced with two surround speakers. Dolby Pro Logic processing is performed by a compatible
A/V Receiver. Dolby Pro Logic II is a later format developed as an improvement to the Pro Logic
format that matrixes into the same channels available in Dolby Digital 5.1 (see below) from simple 2
channel stereo sound.
