Simple DSD modulator for DSC2

[Markw4]

DSD streams are already aligned with ODDR2 primitives...

If that is in relation to possible benefits from reclocking, FPGAs are not good at low jitter, low close-in phase noise output timing. They may have ability to adjust skew, but its not the same thing.

Mark used the PCM-DSD converter you linked resulting a very very bad sound quality.

SQ should be excellent. If you would like to post a link to the file you created I can check the file.

Could be I didn't select well the Precision Filter for FIR filter. Do you have a pic or link how to setup properly because I don't understand Japanese. TIA.

There is an English language page. Also if you browse with Google Chrome you can enable translation. English language manual attached below.

Settings should look like:

Wow that's help a lot, really appreciated, thank you.

The converter seems do the job (file properties show correct info) but no sound, used different players that plays well DSD files F2K & Daphile.

 

[Markw4]

There are two kinds of DSD files: .dsf and .dff
Not all players know how to play both types.
https://hiresedition.com/industry-insights/dsd-basics.html#:~:text=DSF and DFF are related,players only read DFF files.

If using Windows you might try PlayPCMWin: https://sourceforge.net/p/playpcmwin/wiki/PlayPcmWinEn/

Otherwise if want to put the file somewhere that you can link to, I would be willing to try playing it.

Daphile and F2K play both kind of DSD files .dsf and .dff

Try making a DSD128 file, or maybe a DSD64 file. Maybe the problem is the DSD256 sample rate is too high for some part of your system?

Or else you can still try posting a link to the file. Up to you.

N.B, tried from 64 to 256, link to download the 128 & 256 files.

Tried to play the DSD256 file. It plays at the correct sample rate but the audio is null, there is nothing to hear.

Don't know if you have the app installed correctly. Directory on my PC looks like this:

If any of the .dat files got corrupted or something like that, then you might have a problem.

 

[merlin el mago]

Mine looks the same

 

[Markw4]

You might try reinstalling it. Which version did you download, the 64-bit one as shown below?

 

[merlin el mago]

Could be an old version, I will download fresh 64 bit version & try again.

 

[merlin el mago]

Still same problem!!!

 

[merlin el mago]

Tried also the 32 bit version but no success

 

[Markw4]

Have you tried a different wav file?

If so, can you send me a link to a wav file you have tried and let's see if I can convert it here?

 

[merlin el mago]

Before yes, now with last download not

 

[Markw4]

Just send me a link to wav file you want to convert. If it works here, I will send you a link to the converted file which you can then see if it will play on your system.

IOW, I am suggesting to verify if it seems to be a conversion problem on your particular computer. If we doublecheck that and it turns out the problem is indeed with conversion on your PC then we can dig deeper in that direction. Also, can you confirm that you have the correct MS Redistributable package?
