Title: channel arrangement strategy of DTS multichannel audio
Post by: lsmgeb89 on 2013-07-05 16:58:34
I am now investigating channel arrangement strategy of DTS multichannel audio content. I find some strange behaviour of player.
Test result click here (http://www.hydrogenaudio.org/forums/index.php?showtopic=101624)
Note: I test these cases by PS3 connected with 7.1 amplifier. It is standard 7.1 config, it is (FL FR FC LFE BL BR SL SR) by Windows channel notation.
DTS Channel Notation ref DTS Document: ETSI TS 102 114 V1.4.1 (2012-09)
Windows Channel Notation ref: MSDN (http://msdn.microsoft.com/en-us/library/windows/hardware/ff537083%28v=vs.85%29.aspx)

I was confused why PS3 remap 4.0 content in 5.1 environment, but upmix 4.1 content in 7.1 environment and upmix some 6.1 to 7.1, but downmix some 6.1 to 5.1?
What the reason to determine the speak out of content with some strange channel mask?
