# Dolby® E Decoder and Encoder
## Dolby® E Decoder and Encoder
AIXpressor can optionally be equipped with a Dolby® E decoder and encoder. Please see [Adding a Processor](https://wiki.jas.loc/#adding-a-processor) for instructions on installing a new processor.
## Dolby E Overview
Dolby E was introduced in 1999 as a professional audio coding system that allows the distribution of multichannel digital audio within two-channel infrastructures. Up to eight channels of broadcast-quality audio, plus metadata, can be distributed via a single AES3 pair.
## Dolby E Decoder
The decoder will decode all standard Dolby E programs.
**Important -** Unlike legacy Dolby E implementations in which the second program of a 4x2 configuration appeared on outputs 7/8, **AIXpressor always shows the audio outputs in ascending order regardless of which program configuration is being decoded.**
### Input Page
Click on the **Dolby E Decoder button (A),** then on the **In button (B)** to display a running total of the **number of frames received (C).**
(1)(1)(1)(1).png)Figure 1 - Dolby E decoder input page
### Decoder Page
Click on the **Dec button (A)** to display a **list of all parameters (B),** including (but not limited to) the following:
- **Library Version -** The version of the installed Dolby library.
- **Input Signal -** Green indicates a Dolby E signal; yellow indicates PCM audio; red indicates mute.
- **CRC Errors -** Displays the number of CRC errors in the incoming Dolby E stream. The counter can be reset with the **Execute button** at the bottom of the metadata display.
- **Frame Rate -** Indicates the frame rate of the incoming Dolby E signal.
- **Frame Offset -** Shows the offset between the incoming Dolby E signal and the system frame reference.
- **Bit Depth -** Indicates the bit depth of the incoming Dolby E signal.
- **Program Configuration -** Displays the Program Configuration metadata parameter, which determines how the audio channels are grouped within the Dolby E bitstream.
- **Program Description -** Shows the Program Description metadata, typically the name of the program or a description of the program source.
- **Channel Mode -** The Channel Mode (also known as the *Audio coding mode*) indicates the active channels within the encoded bitstream. In the decoder, this ensures the proper routing of the audio channels to downstream devices.
- **LFE Channel -** Indicates whether or not there is an LFE Channel present in the incoming bitstream.
- **Bitstream Mode -** Displays the audio service contained within the incoming Dolby E bitstream.
- **Dialog Normalization -** Also referred to as Dialog Level or *dialnorm*, this indicates the average level of dialog in the presentation and determines the proper level shift in the decoder to ensure proper normalization within and between program sources.
**Note -** The Decode page displays considerable additional information A detailed explanation of all metadata parameters is available in the [Dolby Metadata Guide.](https://developer.dolby.com/globalassets/professional/documents/dolby-metadata-guide.pdf)

### Meter Page
Click on the **Mtr button (A)** to view the decoder meter page. The **Peak Level meters (D)** show sample-accurate peaks for all eight incoming audio channels with a hold function. **Peak Accuracy (B)** is currently fixed at sample-accurate resolution. The **Peak Hold control (C)** allows for Automatic or Manual control of the hold feature. Clicking the **Reset Measurement Execute button (E)** resets the peak hold indicators.

### Output Page
Click on the **Out button (A)** to show the **number of clients (B)** currently connected to the unit and a running total of the **number of frames emitted (C)** from the decoder.

**Important -** Any preset saved and stored in the Dolby E decoder will also be available in the Dolby E encoder, providing an easy way to use the same settings and metadata values. Note that you may receive an error message if the metadata in one of the received programs does not match the program type - for instance, if LFE is activated for a 2/0 Channel Mode of a 5.1+2 Program Configuration. The encoder will automatically correct this, and you may dismiss the message.
