It appears more and more abscent with new releases? What's up with that? I love dts but was fairly impressed with the True Hd soundtrack Star Trek into Darkness. It sounds

Maybe when Atmos is released into the consumer market it would take back control of the market. They can call it Dolby TrueHD Atmos 125 channel not that 125 is needed for the home it can be customized. As long as you have smaller speakers for the surrounds and have them spread spaced along the back wall side walls and ceiling so it pan-though all the individual surrounds and five screen as well oh and the extra two sub bass for the surrounds. What do you reckon on the odds of GRAVITY getting dtshdma 7.1 60% or DOLBY TrueHD 7.1 40%? Will see when its released next year on bluray.

Curse those engineers Always inventing the next best format You fit the same speakers surrounds in the walls and in the ceiling flush mounted so they don't look intimidating. I don't mind seeing x12 surrounds around my room. So if your walls are plasterboard drywall it would be an easy install if carefully planed. I have seen some small dubbing rooms with Atmos and the floor to ceiling was about 1 foot more than my room which is shallow at 7' 8", but doable. JBL Control 1 is a easy model to install in matter of minutes and comes with mounting brackets provided. When first released years ago, the brackets was optional and cost a fair bit. They have a fair good frequency response and handling power and if coupled with a sub for the surrounds would provide an enjoyable surround around the seating in the room. But that's my opinion. As for Dolby TrueHD only newest title I have still is STAR TREK INTO LOUDNESS. That film is mixed far too loud. Softer scenes with effects would have to be at near 0db and if you want to risk your hearing being damaged on some loud scenes that are close on to clipping. The dialouge mix on the film is lousy. I would sooner watch STAR TREK II THE WRATH OF KHAN or decently mixed MONO film like COMA (1978).

I thought the True HD was associated with HD DVD. Maybe that's why its not seen very often now.

It seems to be studio dependent.DreamWorks animation tend to go with True HD more often than not so do Paramount.Fox have always gone with DTS to be honest i would have liked to have seen more LPCM tracks but it only seemed to be pushed by Sony in the early days of Bluray and now has disappeared.

Yeah a big disadvantage of LPCM it had a fixed bit-rate i have the Jet Li film War which has a fixed bit-rate of 6.7megabits!.a lot of people choose Dts-Hd over True-Hd but the True-Hd soundtrack on Transformers Dark of the moon is amazing.Also films such as Spiderman 3 have an LPCM and True-HD track.

I've noticed this even when comparing Dolby Digital to DTS. Although difference isn't extraordinary in that era, I prefer DTS.

This is to create much higher dynamics. I've noticed this even when comparing Dolby Digital to DTS. Although difference isn't extraordinary in that era, I prefer DTS. Dolby Digital used a featured called "dialog normalization". you will often see this in your decoder in negative values like "Diag Norm -4db". It means Dolby track will play 4db lower than the reference level of 85db. On an explosion where a peak of 105db is easily heard, this is a dynamic range 4db wider. You will notice on music tracks diag norm is usually set much lower around -7db. This way the lossy Dolby Digital can match dynamics of a PCM encoded CD. Higher levels on DTS HD MA is due to DTS core tracks which is embedded. Since most tracks are encoded at 20bit or higher, dynamic ratio is no issue. DTS keeps nominal levels high so the embedded backwards compatible DTS core track can still sound decent. Dolby TrueHD has the backwards compatible dolby digital track separate. Its ground up designed for best performance. I notice nowadays they include an extra dolby digital 2.0 track for late night viewing. What a waste!! Most decoders have dynamic volume option anyways.
