| * dca: consider a stream with XXCh/X96 in ExSS as DTS-HD HRAAnssi Hannula2011-01-211-5/+2
| | | | | | | | | | | | | | | | | | | | | | DTS-HD HRA streams do not always have an XBR extension in the extension substream. Instead they can have only XXCh and X96 extensions in there and still be considered DTS-HD HRA. This is also confirmed with Onkyo TX-SR607 receiver which recognizes such a stream as HiRes Audio.

* | dca: use EXT_AUDIO_ID field to determine core extensionsAnssi Hannula2011-02-261-20/+49
| | | | | | | | | | | | | | | | | | | | This avoids the core substream extensions scan when the EXT_AUDIO_ID field indicates no extensions or only unsupported extensions. The scan is done only if the value of EXT_AUDIO_ID is unknown or indicates a present XCh extension which we can decode.

* DCA: simplify lfe_interpolation_fir()Måns Rullgård2010-04-121-10/+19
| | | | | | | | | | This reorders the lfe_fir tables, and drops the mirrored half, such that the loops in lfe_interpolation_fir() can be simplified.
