If your source material is in a different aspect ratio than the ones detailed above, the material should be scaled for the digital cinema output
so that it fits either vertically or horizontally in one of the ’full’ formats
(thereby applying either letter- or pillarboxing).
Audio Formats and Mapping
Audio should be saved in 24 bit at 48,000 Hz and the DCI specification
suggests the WAV file format. For a DCI Mastering the routing of the
audio tracks containing the audio data must be adapted as outlined in
SMPTE 428-3 in the CLIPSTER Edit Tool. The table below shows mapping and labels suitable for audio in a DCP (quoted from the specification for nine channels):
