Audio Sampling Frequency.

[chicagomd]

I currently have the Oppo DVI DVD player that is capable of doing up to 192 KHz Sampling Frequency. My receiver, Yamaha RX-V1500 is also capable of this.

Is there an advantage to a higher sampling frequency as far as audio quality is concerned?

Nothing that can be demonstrated to matter one whit

It is just a matter for the marketeers, not the end user.

I wouldn't go along with mtrycrafts on this one, because higher sampling rates aren't really to do with human hearing range, but more to do with the design of the audio system. 44.1kHz is what's used with audio CD.

Higher sampling rates are used in DVD Audio. SACD works very differently, with a 1 bit technology and v. high sampling rate. I hardly know anything about SACD, but it sounds like a sort of way of doing oversampling (something used in audio CD DAC's - 1 bit D/A converter) all through the production process. ADC's are meant to be, with a high quality DAC, what determines the quality of the digital audio, and maybe SACD targets ADC quality through some sort of oversampling technology?

He questined the audio quality of higher sampling:

I think that is what I responded to, no? There is no real evidence for it. DVD audio can also use 44.1 sampling, all the way to 192

Here is a read for you about SACD:

Thank you both for the input.

I would guess you are better off setting the processing as close to the encoding on the source material as possible, but it sounds like it is just another number I don't need to concern myself that much with right now.

The latest audio D/A convertverters are almost all 24 bit 192Khz sampling. This makes it easy to handle native SACD without conversion to PCM. There is a great deal of variation in price and quality of these as well, from just a few $$ to over $10 for a stereo DAC. Sound quality can be quite different.

Considering that DSD[SACD] operates at a sample rate of 2.8mHz, is 1 bit, and uses a different coding format, I don't understand how a PCM DAC with a maximum of 192kHz sample rate will convert the DSD to an analog output unless a PCM conversion is first performed. But, I do believe that hybrid chipset DACs are around[basicly a DSD and PCM DAC in the same package, that can be switched depending on the source data].
