Audirvana crashes when playing DSD1024

Hello, I’m running A3.5.50 on macos 12.6.3
I downloaded an album with a variety of DSD tracks, some DSD64, DSD128, DSD256, DSD512 and one DSD1024.
When I play the DSD1024, audirvana crashes. The others work fine.
One a side note, the DSD1024 track lists a SPL.Rate of DSD1,114

I’m not sure if thats causing the crash, or if another reason. My DAC is gustard R26

I’ve attached the crash report:

Mac can’t do DSD512 and lesser DSD1024 and further…
you need a PC for those rates…

I’m able to play DSD512 just fine. I assume it downsamples to DSD256?
Then why won’t 1024 downsample?

you sure it is not downsampled to PCM ?

Yes, I believe you are correct!
DSD256 - shows DSD11.2 on my dac and in audirvana
DSD512 - shows PCM352.8khz on my dac and in audirvana 32/352.8khz

So my question is shouldn’t DSD1024 be downsampled to PCM as well ?

does your dac do PCM 705/768, i guess not :slight_smile:

yep

705/768 is for DSD256
x2 for 512
x2 for 1024…

mine is DSD128 max and stop at PCM 352/384

so why not 1024 convert to your max DAC i don’t know,
not knowledgeble enough on that.
maybe Mac thing again or Audirvana on Mac
or your old Audirvana on old Mac :slight_smile:

Touché… lol

MacOS does not transfer raw DSDxxx… All DSDxxx is transferred via DoP 1.1 (DSD over PCM 1.1)… the DoP 1.1 carrier sample-rate for DSD1024 is 2822.4kHz… the maximum DoP 1.1 carrier sample-rate your DAC can support is 705.6kHz = DSD256 (22.4MHz).
:notes: :eye: :headphones: :eye: :notes:

DXD is considered as 24 bit or 32 bit 352.8kHz signals/files… all DSD512 and DSD1024 content is modulated from DSD256 or lower recordings… No recordings are done natively in DSD512 or DSD1024… It makes perfect sense that Audirvana will decimate DSD512 to 32/352.8KHz PCM…

The Nyquist frequency of 352.8KHz PCM is 176.4kHz, where the brick-wall filter will be applied.
:notes: :eye: :headphones: :eye: :notes:

I get why I’m unable to play DSD1024 , (dac not supported, maximum DoP rate etc),
my question is why is audirvana crashing!

@mikeypas
Leave a maximum of 4Gb of memory for the Audirvana and do the test.

Try to put a brick in your coffee machine to grind it… see if it will crash… :grinning:

The most likely answer to your question lays in your system architecture and CPU power and DAC…

DSDxxx is very demanding of CPU processing clock-cycles and your USB bus architecture and USB bus hierarchy, may be causing interrupt delays and buffer under-runs that precipitate the crash… DSD1024 (46.4MHz) is fundamentally experimental and for all intents and purposes is superfluous in all but the most powerful and refined system architectures as a reasonable DSD playback sample-rate and is extremely esoteric in the content realm…
Also, from your original post… you saw DSD1024 being converted to 1,114kHz PCM (probably 1411.2kHz) in Audirvana… Your DAC does not support any PCM sample-rate beyond 768kHz and this may have caused Audirvana to crash… not Audirvana crashing… but your DAC may be puking and precipitating the crash…

So… one or the other is causing the crash…

Just an FYI: “SPL” is the acronym in the audio realm, for “Sound Pressure Level” … The abbreviation for sampling frequency or sample-rate is Fs

  • I’m just using the same terms as Audirvana. “spl. rate” is used in audirvana as sample rate, not sound pressure level.

Anyway, my question was more academic, however, from a software point of view, playing DSD files that are not supported by the DAC should produce perhaps an error message, or stop you from trying to play the files, anything other than crashing. I’m not saying its Audirvana CAUSING the crash, but it is indeed crashing. Maybe Antoine would be interested in knowing that.

As for me, I only had 1 DSD1024 file and I’m not bummed about not being able to play it. Just thought it was weird that DSD512 works even though not supported, but not DSD1024.
I have allocated 12gb memory to A3.5

Did you try to do the test leaving only 4Gb of memory for the Audirvana?

I did, same result!

Your DAC only handles DSD512 and DSD1024 via the I²S port as raw DSD or it can play all raw DSDxxx via the I²S port… So it seems Audirvana can decimate DSD512 (22.4MHz) to DXD (352.8kHz) and this will play on your DAC, but your DAC can’t handle the decimated DSD1024 to 1411.2kHz PCM sample-rate… Your DAC only supports DSD256 (11.2MHz) via DoP 1.1… This is typical with today’s DACs… What is the best solution for folks in your situation? I don’t have a reasonable answer to add to this… I’m sure there are a lot of folks out there like yourself that are learning these things, just the same as you have here…

:notes: :eye: :headphones: :eye: :notes:

The DAC will only play up to DSD256 per DoP.
For DSD512 and DSD1024 Audirvana is converting to PCM.
What I understand is that for DSD512 it is working fine, and for DSD1024 it is having failures, both being converted to PCM.

It could be a problem to have too much memory left for Audirvana.

The solution might be to limit PCM to 352.8kHz.
