HQ Player- limitation to DSD128

[PhilipAC]

Hi all

 

Forgive me opening a new thread, but this is a very specific question.

 

In HQ player, is it possible to convert DSD256 files to DSD128, but leave everything else as native? (I have a server that seems to have a problem with DSD256, while I have a few DSD256 files). And if so, how?

 

Thanks Philip

With "everything else as native" you are missing the point why people are buying HQPlayer.

HQPlayer si about upsampling filters and delta sigma modulators to substitute processing in your DAC.

You can easily convert everything to DSD128, but not selectively. If you want to do something selectively, you need to modify the settings in main window every time the source content format changes.

Thanks Miska

 

How do I convert everything to DSD128 please?

Set the output to 5.6MHz.

I've set the output to 5.6MHz. It now converts all my PCM files to DSD128, but still plays DSD64 as DSD64 and still won't play DSD256.

 

Am I doing something wrong? Thanks for your help.

Look at the File / DSDIFF/DSF Settings. (on Windows, can't remember the menu names on OS X) Un-check DirectSDM. DirectSDM means play the file in original rate, no upsampling.

Thanks all.

 

I have now unchecked DirectSDM and up sampling is happening. BUT only up to 6.144MHz. If I set the limit higher than this e.g. to DSD256 level, the file still plays at 6.144MHz (or such lower number as I set).

 

My DAC certainly plays up to DSD512, so presumably this is a constraint of the server I'm using, which HQ Player cleverly recognises? Agreed please? Thanks

Perhaps you are playing DSD in DoP. Are you on Mac? If it is so, you can only do it through DoP and your max rate is DSD128.

Otherwise, check in Settings your SDM Pack, it should be on "none".

Philip, you began this thread by saying your server only plays file nicely up to DSD128 (aka 5.6mh or 6.1mhz, depending on sample rate family). This assumes you know its your server and not a DoP issue as bogi brings up.

 

Forget what your dac can do potentially; it is irrelevant if your server hiccups beyond DSD128!

 

Set max bitrate at either 5.6 or 6.1, turn off DirectSDM (which you did already) and let HQPlayer up or downsample to DSD128. If you want it always at 5.6 then uncheck auto family and set HQP for 5.6Mhz (or 44k x 128) and make sure right most pulldown on main screen is set for SDM (i.e EVERYTHING to DSD), not auto. If set for auto then all PCM will always upsample only to your max PCM and all DSD will upsample to your max DSD.

[PhilipAC]

Ted- I have done as you and Solstice suggest, and I am now indeed able to upsample or (in the case of DSD256 files) downsample to DSD128. But I would still like to be able to play my DSD256 files at DSD256.

 

bibo01 My server is linux based and I am using DoP i.e. I am using a USB connection. Does this prevent me using DSD256? I thought I could so long as my USB module went up to PCM 705,600

 

I appreciate the help.

[ted_b]

Try going to settings and set SDM Pack to "none" (i.e direct, not DoP). Why? Because DoP for DSD256 is quite rare, and often unusable if even available. Oversimplified but DoP is a band-aid if direct (i.e none) is not workable.

 

And BTW, if you find that setting SDM pack to "none" that you can now play your DSD256 files at DSD256 then try that bit rate for other things too.

[PhilipAC]

Ted- thanks. I get no sound but presumably that's because I need to use a SPDIF connection between the server and the DAC?

maybe i missed it but what are the details about your system -- what are the specs on your server? are you using any software besides hqplayer? what's your dac?

[shadowlight]

Which DAC are you using and what is the USB controller in the DAC. If the controller is Amenero, I believe you are basically stuck @ DSD128.

Are you saying that you are using the S/PDIF input and not USB? If yes, then you need to use USB to go up. And a complete description of your playback chain sure would help!
