Feature Request: Support for PCM1536K and DSD1024

There are currently many DACs on the market that support PCM1536K and DSD1024.
However, JRiver only supports PCM768K and DSD512.

Many? I've yet to see a single DAC that supports PCM sample rates above 768 kHz (from the likes of Schiit, iFi, Topping, FiiO, etc.).

Also you might do a search of the forums, as Jim shot down the idea of DSD1024 a couple years ago. Though somebody once mentioned DSD1024 bitstreaming worked already, though unofficially.

The Denafrips Terminator + does.

That's a $8,000+ DAC. I meant practically priced DACs (in the $150 to $300 range).

[Sky King]

Understood.  Some people have more money than sense.  Additionally there is little to no media out there that is done in native 1024.  If I want 1024 in my system, I simply up sample in the DAC itself.

PCM should theoretically work at any sample rate, there is just no individually selectable resampling option in the output DSP for it.

If you search for DSD1024 DAC, PCM1536K DAC, and PCM1536K DAC CHIP on a search engine, you will understand that the market is evolving. In addition, players and ripping software that support DSD1024 DAC and PCM1536K are also starting to appear. I think they should be supported.

They keep updating the software frequently, but there are no notable additions to the audio functions, so I think it's a good topic.

If you search for DSD1024 DAC, PCM1536K DAC, and PCM1536K DAC CHIP on a search engine, you will understand that the market is evolving.

Evolving doesn't mean it's practical or even really a good idea. Content for sale for DSD for example, above DSD64 (SACDs) and DSD128 (specific recordings, e.g. classicial, available as digital downloads) there really isn't anything. Maybe test files, maybe obscure albums here and there. That's pretty much it, there's no major album releases, except for SACDs which are DSD64.

Same goes for PCM content above 192 kHz. All the major digital download stores max out at 192 kHz with anything above that again being mostly obscure albums, test files, etc. 96 kHz and 192 kHz seems to be the max 'standard' for "hi-res".

Who's recording their music in DSD above DSD64 and maybe DSD128 and PCM above 192 kHz? Seriously? Any content above those are likely resampled anyways (and to be fair most content available at those rates are already resampled, but that's a different can of worms to tackle).

In addition, players and ripping software that support DSD1024 DAC and PCM1536K are also starting to appear. I think they should be supported.

Honestly, I think it's pointless to resample existing lower PCM and DSD content to higher rates or to even rip things like vinyl to those rates. You're not gaining a single thing at all (depending on the recording frequencies likely don't go above probably 96 kHz at the most anyways so there's dead space), and it's always a lossy conversion and it's very resource intensive. Also if you're converting them to files and not doing it on-the-fly during playback, sizes of the files are enormous compared to the source. So it's not practical at all. I would also say this for PCM above 192 kHz and DSD above DSD64.

Just because DSD1024 and 1536 kHz PCM is available doesn't mean everyone should be using it (and most won't), as it's mostly a marketing gimmick. It reminds me of MQA in a way being a gimmick too, and we all know how that went.

But... chances are both already work in MC, assuming you set DSD bitstreaming to bitstream all DSD sample rates and as Hendrik mentioned there's no max sample rate set so as long as you don't use DSP (e.g. output formatting) it likely works too.

It's just they're not added in the GUI as output format options or anything like that. It's sort of like you can technically get MQA working in Media Center too, even though it's not 'officially' supported with any specific options. But as long as you have actual DSD1024 or 1536 kHz PCM audio files it *should* play them back as-is, you'd have to try it if you have any.

I guess part of the issue is how much work does it take to support one more DSD sample rate?  It seems like it could be a very quick addition, although there may be issues of doing it that I do not understand.


Blue Coast Records is one company that is dedicated to high resolution audio, especially DSD. She records at up to 256 MHz. She also records in analog and samples that up to 512 MHz.  It is a small company of minor artists but it shows that there are people out there who believe in high res and in high res DSD.  She has ben nominated for Grammys for her work. Small - yes. Dedicated to high res audio - yes. Interesting work - yes. I do not think she does 1024, but she certainly does 512 Mhz without upsampling. She samples it  directly from analog. Take a look.

And, by the way, I do not think MQA was a gimmick. It was an ingenious solution to a problem that, it turns, didn't really exist - namely, how to deliver high res audio in a limited bandwidth environment.

Good site for DSD: https://www.nativedsd.com/

I've bought a few PureDSD recordings in DSD256 (5.1 channel) and DSD512 stereo.

Mostly classical and jazz, but some really good music that sounds brilliant via my exaSound DAC
