Channel Growing – increasing the number of audio channels within a media file
Whilst not an application itself, channel growing is an important function that may be needed to realise specific workflows. In essence, this converts a media file to a media file with a greater number of audio channels. For example, you could start with a two channel MXF file, and end up with an eight channel MXF file. These additional channels may be required, for example if you want to upmix a stereo file, and keep the new 5.1 within the same MXF file.
The diagram shows just how simple it is to configure channel growing.
Channel growing has to be as the first step in a workflow, but can then be following by any of the available modules. The diagram below shows the upmix example.

Reducing the number of channels
Reducing the number of channels in a file is often a requirement after downmixing, or after Dolby E Encoding, and is also extremely simple to achieve within Engine.
Here is an example in context, showing how simple it is to choose which channels to keep and which to throw away.
This last diagram shows an 8 channel file that contains stereo on channels 1 & 2, and 5.1 on channels 3 to 8. All we want is a stereo file containing a Dolby E encoded version of the 5.1 and this workflow will achieve this. Creating a workflow like this takes just a few seconds with Engine easy to use editor, and there is no difficulty of mapping the right audio in to the right places – our software handles everything for you.
