About Working with Dolby E

Dolby E is a professional audio coding system, developed by Dolby Laboratories, that allows you to distribute 8 channels of high-quality digital audio (plus metadata) over existing two-channel audio infrastructures (AES-3 pairs). Post-production facilities are able to provide a variety of sound mixes, including foreign language tracks and discrete 5.1 audio over the same pair.

The frame rate of Dolby E encoded audio matches that of the accompanying video, allowing you to insert or assemble edits in Flame without audio pops or clicks and without having to use Dolby E encoders or decoders. This is very useful in cases where you need to modify a clip, for example to create a different version or to reformat for TV broadcast, and put the clips back on tape. Dolby E works with standard PAL and NTSC video frame rates of 24 and 23.98 fps at a sample rate of 48 kHz. A DP571 Dolby E Encoder or a DP572 Dolby E Decoder is only necessary if you need to create original content with Dolby E encoded audio, or to monitor the encoded tracks.
