Dolby E is an audio encoding and decoding technology that allows up to 8 channels of audio (mono, stereo, 5.1 or 7.1) for a primary program and optional ancillary programs. The 8 channels are compressed into a digital stream that can be transferred between compatible devices and stored on a standard stereo pair of audio tracks. The most elaborate mode in common use is Dolby 7.1 which uses all eight channels to provide surround sound. The Dolby E option enables checks to ensure that Dolby E has been created correctly and transferred transparently through the broadcast chain unaffected by routers/switchers, satellite links.

Peak audio levels included in the Dolby-E meta data packet are displayed allowing the user to select the appropriate set of meters to display Dolby levels which will follow the selected Dolby E source.�

Logging for Dolby�errors, timing, common metadata and program metadata can also be setup. Dolby E errors can be captured in the error log to allow analysis of the live data stream.
