I wouldn't be so sure about that.

 

The thing is that the emulation code has to fill in the "missing" samples if you choose the sampling rate too high, and to my understanding this is most of the time done in a very simple way (to not harm emulation speed that much), whereas otherwise it will output the exact same thing that the hardware actually would spit out (at least in theory), where then its up to the hardware or the driver to upsample it to something that is then being actually output (which is usually much better).

 

To stay with your example:

It would be the same like if you would extrapolate a SD picture to 4K, but use a rather crappy upscaler for that, and then optionally even scale it back down to HD (which would happen on cards that are not configured for/support 96kHz output).

While ideally you would rather want to have an awesome upscaler going from SD to HD directly.

 

EDIT: apart from that, i found out why you cannot choose 96kHz, will be fixed in the next build.

I never did hear a resolution to this. I am using the latest VPM (October 31, 2016 build with the ddraw fix) and am getting warbly/slow sound in ST TNG. I opened a seperate thread regarding this here: 

 

I never did hear what the resolution was to this question regarding optimal sound values:

 

VPM: synclevel setting in setup window, 'threadpriority' and 'audio_latency' registry entries -> what are the 'optimal' values here to avoid stuttering?

This thread is old.  The most recent info is here, and on another site we aren't allowed to talk about here.   http://www.vpforums....vpinmame&page=1

 

There have been a ton of changes to vpinmame lately... too many to summarize, but if you want to read up you can start there.

I read all 23 pages of the VPinMame thread linked there, but nothing indicates optimal sound settings to eliminate the broken cassette deck sounding slow downs. P.S. running the Oct 31, 2016 build from that thread.

 

Is there documentation on all the VPinMame registry entries (there are a ton per game) that I can start toying with? It seems the VPM UI sets only a handful of them.

I would post for help in that thread, including cpu specs and what version you are running.

Sounds good, thanks
