Im not sure what this means? Is dts hi res still compressing them? Why would the dts master have lower bitrate?
Im just curious because I am not familiar with dts hi res audio, if anyone can explain if theres anything different.
I have the encoder suite studios use to encode DTS-HD MA and DTS-HD HR etc.. and actually to encode DTS-HD HR after you choose your amount of channels and DTS-HD HR and input your wavs the choices for encode are just bitrates. In my opinion I see little point in using DTS-HD HR instead of DTS-HD MA since its lossless instead of lossy and uses little more bitrate.
I doubt there's going to be any audible difference between the two.
Im unfortunately seeing this pop up in pal country. The french version of the departed with a nice avc encode has hi res, the new higher bitrate planet earth has hi res as well.
I guess I could remux the departed, but then i would loose menus.
House of Flying Daggers: Mandarin track
LPCM (US) 4608 kbps
dts-HD HR (Aus) 2046 kbps
dts-HD HR (Fr) 2046 kbps
dts-HD MA (TW) 2047 kbps
Perhaps if people doing encodes like the above realise this they would have chosen MA instead.
DTS-HD High Resolution as of now is not just for smaller bit rates but for BANDWIDTH constraints! DTS Master even with a low AVERAGE bit rate the PEAK bit rate can be as high as 27mbps! If any of you have DTS MAS encoder run a high resolution PCM file (like 96khz/8 channels or 192khz/6 channels) then take a look at the peak bit rate graph and you will see that peak bit rate higher than DTS High Resolution can be sustained for a bit, combine that with multiple DTS Master tracks and you have a serious Bandwidth issue.
So yes DTS High res does have a place but it should have had a variable constrained bit rate (much like some forms of AAC) so 754 core with the extension being variable bit rate like DTS-MA but only up to say 2046, 2304, 2559, 3018, 4608kbps, etc. Variable bit rate can sometimes be rough for bandwidth constraints, very unpredictable. 96khz/24bit/8 channels in LPCM is a very high constant bit rate but DTS Master in tracks that consist of varying levels of activity correlating to high and low bit rates (simply put)...... Ill see if I can post some screenshots from my Master Audio encoder so you can take a look at bit rates, settings, etc....

When we come to high resolution tracks nobody would want a lossy encoding. I have concert Blu-rays and audio only Blu-rays with 24/96 or higher in dts-HD MA and there's no bandwidth issue.
A 6CH 24/192 PCM track would be 27.6Mbps, the max. audio bandwidth allowed on Blu-ray, and if a dts-HD MA track ever reaches that, which means it can't compress at all then it doesn't make any sense. Even the official dts-HD Audio whitepaper doesn't give such a high figure.
