16/44.1 vs 24/96 and higher sample rates

[haisaikat]

Looks like the output is being downsampled by Windows 7.

You can fix this in the Windows 7 Sound settings. Control Panel > Hardware and Sound > Sound > Double click on HDMI Audio Device > Click "Advanced" tab, select 24bit-96Khz. (It must be "16bit-48Khz" there now).

That should fix it

Actually that setting was selected but due to some detection problem it was not getting imposed. But thanks since following your suggestion I looked over there and after playing around it worked.

Now I have one question, earlier in this thread I was recommended that upsampling improves the audio. So I selected from control panel ? audio options the sampling rate as 24 / 192 and when I played the same on AVR the AVR is also showing the 192 sampling rate from input. But is the proposed upsampling happening here? Although I did not notice any improvement.

I doubt that upsampling gives actual improvement..it is like fill in the blanks..if properly done, then yes it will.

Anyone who came to last Chennai hifi meet can really appreciate the higher resolution in music. I am not a big believer in bit rate. But, firm believer in sampling rate. Kudos to Siva, we experienced the benefits of using musing with higher sampling rate than CD. One word to describe it -- Dynamics. It was undeniable. CD sounded harder. Whereas HD tracks sounded with much better dynamics and so soothing for the ears.

Good to know it worked!

About upsampling, I don't really know enough to comment, but my uneducated guess and experience with experimentation in my setup is that it makes no improvement whatever. In fact (this could be psychological), I felt that changing the sampling rate takes away something from the music.

FYI: CA whitepaper explains upsampling and audio filters.

Even if you source file is 24bit/192 khz, it is passing through your AVR filter (which down-sample to its standards), therefore you never notice any quality difference. I had similar experience while playing files with of higher quality through AVR.
But when I played same files through Denon Amp (PMA-510AE) with direct-mode (without passing through its filter) I noticed difference in quality (improved)!

Please check this, my AVR Denon 1911 does support 24/192 mode and note that under Stereo mode I do see under input signal info the sampling rate as 192

Hi musicbee, one question if the software just simply upsamples how can it improve the quality since in the low quality format what is already lost is lost?

Sorrry... missed the question but I personally have not heard any difference with upsampling.

Sorry.We are coming to equipment comparisons! In my case AVR HT-R380 support 24bit/192khz DAC. But still sound quality is NOT equal to DENON PMA-510AE!!

My conclusion (Specific to blog subject): Technically 24bit/96khz sampling rate is better than 16bit/44.1khz.but..it depends on your setup also (Player + Speakers + Amp).
16bit/44.1khz file system is just sufficient to deliver VERY GOOD sound (Clarity + Dynamic + Sound Stage)! But againthere is very little margin for error (w.r.t.recording). This is the reason why it is acceptable format for CD recording worldwide! (Not having reference for the article which I have read).

If you feel CD quality is NOT upto the mark.when your setup is of best quality.then recording is poor! I have experienced poor quality in CD recording. Therefore a good quality CD (16bit/44.1 khz) worth comparable with 24bit/96khz file (vinyl rip). You will feel negligible difference!
Thanks all members..please put your reviews.

Intellectual waffle. Too much for me; I'd rather break my head over something technically hard to understand.
