5.1-Channel Production Guidelines Introduction
1-4
5.1-channel audio typically consists of five discrete, full range main channels (Left,
Center, Right, Left Surround, and Right Surround) plus an optional band-limited Low
Frequency Effects (LFE) channel for added bass (the .1). Dolby Digital bitstreams
deliver full frequency bandwidth main channels, from 3 Hz to 20 kHz, and a limited
frequency bandwidth LFE channel, from 3 Hz to 120 Hz. Current Dolby Digital
encoders accept word lengths of 16, 18, or 20 bits at sampling rates of 32, 44.1, or
48 kHz. The Dolby Digital algorithm provides 24-bit resolution, and future versions
may extend sampling rates to 96 kHz. All multichannel programs carried within a
Dolby Digital bitstream, can be downmixed (see Section 2.2) for compatibility with
Dolby Surround, stereo, or mono systems.
