24 Bits 48000Hz VS 192000Hz, Which one should I use to listen my games and my 48KHz/96KHz songs?

post #1 of 17
Thread Starter 
I just need factual evidence that 192KHz make the sound worse, I've heard this many times but I DO can hear a difference between the two, I feel the 192KHz to be more of a quality warm sound, while 48KHz after hearing 192KHz sounds like a little bit more pitching, I could even call it Placebo effect, but I don't know, so here I am, asking to you Audiophile with wisdom and experience on the matter.

I got integrated Audio, the best one there is for integrated Audio (At least that says on the Asus Sabertooth MOBO) it's a Realtek ALC High quality sound and I got it paired with a nice Logitech Z623 2.1 System, which is capable of playing 192KHz at the highest sound depth and quality.

I've heard around that 192KHz just supersample the sound, somehow making it worse, My ears would like to disagree but that would be subjective, I'd like to know some actual objective facts about these two frequencies, or the most recommended frequency. I'm on 96KHz, but I'd like to use 192KHz for my PC games and songs.

What do you think? Should I just put 192KHz on my driver and call it a day? Or should I choose a different frequency without drawbacks? is there even any drawback to using 192KHz? The frequencies are all selected on the driver, picture below.

There are no audio frequencies beyond 22KHz on standard Red Book Audio, increasing your sampling rate just requires more cpu cycles and burns more electricity. Your Logitech speakers dont even have tweeters and likely dont produce significant output above 16KHz anyway.

48000hz should be fine for you. If you don't have an external or dedicated audio card OR you dont have a good pair of headphones, you will not notice the difference.

for most its just a placebo.

Like 99% of music is 16 bit 44.1 KHz

The degradation of quality comes from forced upsampling, which is generally bad.

What about 24 bits 44.1KHz, does it still upsample the sound?

Also, from your answer I take that unless I get songs at 192000Hz I should never pick that frequency, or it'll upsample it and degrade the quality, even for video games, right?

I thought that if I choose 192KHz and play songs at 48KHz those songs would only use 48KHz out of the 192KHz bandwitch, or they would get scaled up increasing somehow the sound quality, but now I see it's just the opposite.

the first paragraph means nothing with DBT.

Anyway, just 24/96 would be fine as it negates every possible negative from lower sampling rates / bit depths.
Upsampling up to this point is fine.

Saying your Logitech Z623 2.1 system is capable of playing 192 KHz audio is like saying my Volkswagen drives like a Lamborghini Countach. They both have 4 wheels and an engine, the similarity stops there. Your Z623 is analog only, so it's only going to play back 35-20 KHz analog signals (according to the Logitech specs), and won't even do that accurately due the component selection in the unit.

If you like the oversampling that 192 KHz 24-bit does for your 16-bit 44.1 KHz source audio, then by all means go ahead and use it. But the audio quality is entirely subjective, and in the "ears" of the beholder.

You can't make a low-resolution compressed audio sample from a game or MP3 sound any more accurate than it already is. You might be able to adjust the bass, treble, and stereo reverb to more to your liking though.

However if you are using controlling the volume digitally, using a higher bit depth is advantageous as it allows for more headroom as when you adjust the volume down, you are shedding bits (-6 dB being 1 bit) and volume up = adding bits. Using a higher sampling rate often results in less distortion from the source as well.

That is of course if the source doesn't auto-switch based on the digital file's sampling rate.

So just set it at 24/96 regardless.

Thanks, it clear most of the doubts, I'll be seething 24/96KHz, but... The guys above said my logitech Z623 aren't able to play over 35KHz frequency due to its analog nature, which somehow is limiting it to only 35KHz, so beyond 24/35KHz it wouldn't make any difference, or I am not understanding it right?

Thank you Astralite. People constantly ask me about Logitech speakers such as these without ever using their eyes along with their ears. biggrin.gif Tweeters are not hard to spot......... And, no I am not picking on the OP of the thread.
