DTS vs 192khz digital

[ChaseD13]

What would sound better comming out of a soundcard, through a receiver and to headphones/speakers....

the new auzentech does 192khz while mine only does 96khz....but they both do dts.


shouldnt dts be better as it is a higher bitrate? why would u even want to use 96/192 khz when you have dts

I think dts offers only compressed audio which would not sound better.

I think your confusing sample rate and Biterate. 96kHz and 192kHz are sample rate how many time/sec you have a data point. Imagine a sine wave how do you represent it in digital. You take many data point and connect them together how many point/sec is the sample rate

Here an image from wikipedia about pcm that digitalization of a sinwave

So with 192kHz you have 192k point(sample) /sec to represent the sound wave


Also
DVD-video standard for DTS is at 48khz


Bitrate specify the size of the files per second.

EDIT: For example a DVD-audio with 24bit 192kHz stereo is 9.216 Mbit/sec (according to this site not quite sure if it's accurate but it seem in the good ballpark)

A 6 channel version (similar to DTS 5.1)would be 27.648 Mbit/sec of course those are uncompress LPCM stream

so...i should get better sound when i output in the 96khz as opposed to dts.

but for some reason i get better sound out of dts. mab just my receiver is better at decoding dts than pcm?

maybe my card is better at outputting dts than pcm?

I'm kind of changing the story here, but im now wondering why the compressed dts sounds better than the 96khz pcm

no point setting your card to encode live and output DTS (can it even do that?) unless you use digital output and want surround for gaming

just output whatever the input is

The first question is do you have a 96kHz PCM source? Something that has been recored and stored at 96kHz(or higher for recording) What do you compare when you said DTS is better than 96kHz?

If you take your DTS sound then converted to pcm then upsample to 96khz it may sound worst if the conversion is not very good and add artifact.

Secondly are we talking about your sound card outputting 96kHz digital and your receiver accepting 96kHz digital? Third does your sound card upsample or leave everything as is?

What sound better depend on first the source files and it's limitation.(ie crap in crap out) Secondly on how good all the component eventually end up converting all those to analog sound at a suitable level to drive headphones/speakers. And which systems has better component.

Now a question is why do we need 96kHz and 192 kHz if all our sound is cd quality 44kHz or 48kHz. Well search the forum on 192kHz upsampling and see the discussion on why it's better or not really better. But in sound card it seem that alot prefer bitperfect meaning no changing at all of the signal before the dac give you better result.

EDIT: Also now there is DTS 96/24 which is DTS at 96kHz and DTS-HD which can do DTS at 192kHz but I'm not sure how much market and availability those format have.

truthfully, now that i've done a closer comparison the only difference i can see between dts/ddl encoded music and pcm is volume. dts is louder and it seems that the sound is more forward (out of both speakers and and phones)



all of my files are minimum 192 mp3..but ive been testing with flac files.

and yes, i have been talking about the output on my soundcard. my receiver is capable of decoding the dts/pcm.

oh well, forget about it...
