I have RME ADI-2 Pro FS R BE with Windows 11 (MADIface driver).

RME ADI-2 Pro supports 768Khz and I know that Windows can support only 384Khz and that is working properly.

The problem is that in Vienna Synchron Pianos I can use it only with 192Khz. If I set it to 384Khz than it does not work. It changes in MADIface setting automatically to 44.1Khz when I close the settings window in synchron player. Can you please explain why is it so? Is 384Khz splitted to 2 channels - OUT1 as 192Khz and OUT2 as 192Khz or why is it not working with 384Khz?

Thank you very much.

Hi Brcinskij,

Unless you make music for dolphins there is no reason to go over 44.1 / 48 kHz when working with samples.
Even then: There are no sample libraries with this sample rate, so you will not get any additional information out of the libraries. You should choose the sample rate based on what the target format should be (for example CD, DVD, movie, YouTube, ...).

Humans can hear up to 20 kHz, 44.1 kHz can reproduce frequencies up to 22 kHz (see: Nyquist rate).
In contrary: Working with these high sample rates can have negative side-effects that can reduce the quality.

Best, Ben

In this context, it is always worth referring to the famous White Papers by Dan Lavry, undoubtedly one of the most distinctive figures in the field of AD/DA converter design:

-> The Optimal Sample Rate for Quality Audio

Long story short: "60 KHz would be closer to the ideal." :-)

More noteworthy papers by the same man can be found here

Thanks, here are the conclusions by oversampling from Dan Lavry:

Theoretical sampling retain all signal information. Practical considerations take advantage of higher then theoretical
sampling rates. Most analog to digital converters take advantage of higher sampling rates to overcome undesirable high
frequency rolloff problems. Oversampling simplifies anti alaising filtering requirements and provides room for phase linear
transfers. Storage and processing economy requires conversion from higher to lower sampling rates (downsampling). Data
found in compact disk recording and similar formats is often oversampled prior to digital to analog conversion, to simplify
anti imaging filtering.


I dont know, but f.e. it is not only me, but some other listeners said it too. We listened to some songs streamed via Tidal, originally recorded at 44.1 KHz and oversampled to 192Khz or 384Khz and there was really noticable difference. We heard more details at 384Khz compared to 192Khz. We have tested it again and again with the same result. That was the reason why I wanted to test it in Synchron Player this way and I did not understand why I could not get it work with 384Khz. I wanted to compare it (192 vs 384), if I would hear any difference like I did with Tidal. Hmmm..
