DTS vs Dolby formats

[RajithKumar]

Hi Guys..
Gud Noon..
I just starting this thread to know your views on the DTS & Dolby formats...
The below are my personal views..
Watched different movies with these formats..but the sound from the DTS formats was very nice when compared to the Dolby formats.
whenever Dolby formats are played ,the volume level and bass is becoming low..But I'm not saying the dolby formats are bad..but when compared with DTS ..i still prefer DTS is better..

Expert views and reviews please..

Thanks in Advance..

DTS lossy 5.1 format have 2 constant bitrates... Half bit rate (748 Kbps) & Full Bit rate (1548 Kbps) While doolby has variable birates like Mp3.... Meaning the bit rates can vary.... Hence the difference....

But if you listen to DTS & DD with same bitrate, you may not hear any difference @ all....

Dolby formats play back 4dB quieter due to a feature called dialnorm. Turn up the volume on the Dolby formats and they will sound as good as DTS formats.

I have different opinion.Yes DTS is superior technically,still with Yamaha AVR,DD sounds more dynamic and musical. DTS can sound sometimes sharp in some systems.
Again it depends on original track recording quality.

As you have a Denon receiver you are feeling that DTS is comparatively good to Dolby. But if you hear it in a Yamaha receiver you will change your opinion hyeah: (albeit both the formats have similar bit rates). I have seen and also some of the FMs also perceived that the Yamaha decoder actually decodes the perfect configuration for Dolby rather than DTS. In fact after hearing this difference I know try to download a movie with DD 5.1 and go with DTS only if I cannot find a DD audio movie. The surround effects in the DD are blown to the perfect timing on my Yamaha for the DD audio formats. I am not sure how this difference as all the receivers support both the formats but when you actually listen to them they sound a bit different on different formats

Dolby Labs doesn't reserve a special version of their DD decoder for Yamaha receivers. The same decoder is licensed to ALL manufacturers. If you're hearing a difference, then it is something after the decoding step (e.g., D/A conversion, analogue stage, etc).

Decoding 'better' is like being a little bit pregnant. You either are pregnant or not. Likewise, the decoder chip either decodes the DD bitstream or it doesn't. Besides, what would a 'better' decoder do? Put the left channel information further left?

I think spiro in the earlier post has given the correct interpretation compared to mine. I am not saying that the same bitstream gets decoded differently in different receivers but the end result is different. What I felt is that the surround effects on a DD audio in my Yamaha comes out very good compared to a DTS stream.

DTS almost always sounds better than Dolby. This is a universal fact

DTS always sounds better than Dolby in Onkyo HTS350

I am not saying that the DTS is inferior to Dolby or the other way around but that the receivers are decoding them differently (or sounding different) in my setup. I some how hear better surround effects on a DD 5.1 audio rather than a DTS 5.1 audio in my Yamaha and hence try to download a movie in DD most of the times.

 

[Rockfella]

I understand, trust me DTS is better.

DTS & Dolby are both same when they are of same bit rate.

Play DTS HD audio of King Kong and play it you will just feel each and every nuance and effects in the movie. Also take Dolby Tru hd from Dark knight it blows you away like anything. MI- Ghost protocol has Dolby Tru HD audio, it will bring the best possible sound effects for the movie. So both the surround formats have similar kind DTS & Dolby have similar power but it totally depends on the bit rate and mixing done.

W can give lot of examples for those formats.

The only reason I replied to your post originally is because you mentioned the Yamaha "decoder". I wanted readers to be aware that it's the same decoding used in every piece of gear, from the cheapest HTiB to the most expensive pre-pro.

If you're hearing a difference, then it is due whatever circuitry Yamaha is using after the decoding step, such as their choice of D/A converters and analogue gain stage. Those things can make for a different end result.

Dolby Digital is sometimes too bass heavy while DTS is always very sharp with the right amount of bass punch.Dialogues seem to be more clear and on your face kind in DD than in DTS.

my 2 cents

 

[sdurani]

DTS & Dolby are both same when they are of same bit rate.

When it comes to their lossy codecs on DVD, Dolby Digital is much more efficient than DTS, so it can yield the same or better results with a lower bit rate. For example: half bit-rate DTS at 768kbps starts rolling off the sound at 15kHz while DD at 448kbps is flat to 20kHz.

It isn't uncommon for some lossy codecs to be more efficient than others. The AAC codec that Apple uses for iTunes downloads gives better fidelity (faithfulness to the original CD) at 256kbps than MP3 does at 320kbps. So DD being more efficient (better sound at lower bit rate) than DTS is not unusual in the world of lossy audio codecs.

For lossless codecs on Blu-ray, like Dolby TrueHD and DTS-HD Master Audio, bitrates cannot determine sound quality. Lossless, by definition, means bit-for-bit identical to the original. Doesn't matter if one uses ten times the bit rate of the other, the end result is always 100% identical. There is no such thing as being 'more identical'. It's either a bit-for-bit copy or it is lossy.

 

[Santy]

The same ol' Coke Vs Pepsi debate.

I thought we have graduated to Dolby TrueHD vs DTS-HDMA :lol:

 

[RajithKumar]

Yes Santy ..both are losless formats..I have not yet used Dolby True HD but have used DTS HD master audio ..It was awsome..
Moreover most of the Blurays globally were using DTS HD master audio higher than Dolby true HD..
Recently Sony Bluray disc corporation recently posted a user feedback about this ...since they were in the dilemma of whether to switch from Dolby True HD to DTS HD master audio or not...
In this thread..I'm expecting ,we can get more info the above too...
Also heard Dolby has lost many shares to their rival DTS on this...Don't know how far it is true.....

 

[RajithKumar]

However My stand is on DTS & DTS HD master audio side...may be because of my hearing taste..

 

[RajithKumar]

Any Feed back on DTS Neo x & Dolby Pro IIz...???since it is a 3 dimensional surround format..the experts can share their views..

 

[spirovious]

..I have not yet used Dolby True HD but have used DTS HD master audio ..It was awsome..
..

DTS HD Master is better sounding than True HD,even Dts High resolution audio in Yamaha too. DTSMA has better resolution and details.Also instruments sounds very good with good sound stage and space.
