Introduction
This section explains the mix file structure used to create the audio mix files
for Imagestore HDTV. Please see the Standard Mixfiles section on page 221
for the extended information and in-depth functionality of the standard
mixfiles.
The conceptual mixer arrangement used in Imagestore HDTV is based on the
Imagestore 2 Easysound audio model. This is an A/B mixer followed by a
number of cascaded voice-overs.
By using the same conceptual model backwards compatibility with the
Easysound audio automation protocol can be maintained, however, there are
a few subtle differences.
Internally, the Imagestore HDTV has two voice-overs as opposed to the two
stereo pairs in Imagestore 2. A mapping is performed:
