Audio (Channels) Tab

It contains the following settings:

Streams (audio tracks)

The list of streams is visible in the Streams window. When you select a stream from the list, you can see the details for this audio stream in the next Stream Details window.

To define/remove/edit a stream, press the Add/Del/Prop button respectively at the right side of the window.

To change the order of the streams in the stream list, use the Up and Down buttons.

When you press the Add button, the set-up window will open.

Enter the name of the new stream in the Name field.

In the Preset field you can select a preset for a channel mapping from a drop-down list. Here you can see a list of the most popular channel mappings.

For example, if you select Stereo, the channel mapping will contain a [Front Left] and a [Front Right] channel. If you select 3 front LFE, there will be: [Front Left], [Front Right], [Front Center], and [LFE Subwoofer].

In Mono Channels Count enter the number of mono-channels, included in this stream.

Note: If you have selected some preset from the Preset list, then the number of the mono channels appears automatically, and you cannot change it.

If you select the Preset to be Unknown, you can enter the number of mono channels manually, and you can define your own channel mapping into the Channel Mapping area.

Channel Mapping

By default, when you select some number of mono channels, in the Channel Mapping field, you will see the most popular mapping types for them.

Note: There is an option, in which the Channel Mapping could be disabled. If you would like to disable these settings, please contact X-Pert Support team for further assistance on chat button https://x-pert.tv/support/, via e-mail at support@x-pert.tv or phone +359 8 77 66 33 51.

If you select 2 mono channels, the Mapping will contain a [Front Left] and a [Front Right] channel.

If you select 4 mono-channels, the Mapping will be: [Front Left], [Front Right], [Front Center], and [LFE Subwoofer].

You can delete one or more of these mono-channels by pressing the Del button to the right of the Channel Mapping area. Then you can add a new channel for audio mapping, by pressing the Add button.

To change the channels’ order, just select one of them and move it up or down in the list, by pressing the Up or Down button.

NOTE: If you have selected some preset from Preset list, then you cannot edit the Channel Mapping

Important: In case the available in-file mono-channels are different in count than the ones, selected for the output (for example, you have 2 mono-channels in file, but define 4 mono-channels for the output), the re-mapping is made by the software up to the most-popular re-mapping rules. If you want to make your own re-mapping, please, ask our X-Pert support team (support@x-pert.tv) for assistance.

Audio Level in dB – Enter a value here for changing the output audio level of the current stream. The default value is zero (0), which means that there is no change. If you enter one (1), the output audio level will increase by one (1) dB. If you enter minus one (-1), the output audio level will decrease by one (1) dB.

In the Input Type field, you can select from a drop-down list a type for the sound in this audio stream, like “dialogue”, “music and effects”, “commentary”, “voice over”, etc.

In the Output type field select the output encoding method – PCM or Dolby Digital.

NOTE: Currently, Dolby Digital output is supported with a Deltacast card only.

Output settings – This button is activated when the Output type is Dolby Digital. It provides a set-up window of the Minnetonka SurCode for Dolby Digital.
