Audirvana Plus 2.5.1 with PCM->DSD Conversion

[odelay]

While heat problem does sound a little concerning, it's encouraging that it can still work on old Macs (like my 2010 mini...)

 

I'm still waiting for my DSD DAC, but be sure to test it as soon as I get my greedy hands on it.

 

Kudos to Damien, Mans, Jud and co. for making this happen :-)

Apple's desktops are limited to the mini and that over expensive spittoon, so the choices of high power Apple computers is limited to cope with the current A+ PCM-DSD. It's early days yet, but it's great to see. Means an end to sample rate change delays, since the output is always the same, PCM or DSD played files.

Make that third, as you can also do PCM -> DSD with Foobar2000 on Win!

 

Do we care about Foobar2000..?

Good news first, plays at 64 and 128 no problems with playback, no skips or pops. Things to be careful about is the CPU temperature. At 64 the CPU overall runs at 27 percent for about 6 minutes then drops back to 1 - 2 percent for about 4 - 5 min. While it's at 27% the temperature starts climbing fast, I stopped it when it past 85 deg C, and turned the fan control up to 100% (5500 rpm) and tried again and it still reached 82 deg C occasionally. That's on a MAC Mini 6.2 Quad core, i7, 2.6Ghz with 16GB of memory and no other programs running. At 128 it just stays at 28 - 30% and the temp just keep on climbing. Even the case on the Mini got hot. HQ Player doesn't get any where near that hot running at 128, I don't even think I've seen it get that hot at 256. With some more tweaks hopefully A+ will match HQP in that respect. As an old electronics engineer I'm just not comfortable with those temps on a continuous basis.

 

Sounds like your heatsink might be in need of new thermal paste and maybe a cleaning. A properly cooled i7 shouldn't exceed 70°C or so even under sustained full load. CPUs are usually rate for a max temp of 105°C so if it holds steady at 80°C it should still be fine. If it keeps climbing there's more cause for concern.

Here is the new build with Mans new filters (you'll have 11 to choose from), they are not sorted by quality. But the Type A should be safer for DACs that have a tendency for noise.

Please tell me if you encounter noise with a filter, the DAC model, and the song with which it happens.

And the filter you prefer

 

CPU usage is due to the use of high quality filters. The heaviest computation is the upsampling done using iZotope 64bit SRC. You can reduce quality though, but I don't think this is the objective.

FYI, I've parallelized the PCM to DSD whole process to use up to 4 CPU cores.

 

Have a great WE!

Damien,

 

How can we read the filter settings ?

The letters A, B and C are the generations/versions of the filter coming from mansr, 0 being the raw conversion filter ?

The subsequent numbers are tunings that you build to prevent some problems with some file ?

 

Some filters sound incredibly good !

[mansr]

Some filters sound incredibly good !

 

It would be helpful if you could elaborate on that. Also, what DAC do you use?

Wonderful, my files in ALAC (Goodbye HQplayer!) work without problems with my Mytek DSD 192 in DSD128 with A+ 2.5.0.6 … and what a sound!

 

 

I just noticed that the ventilator of the Mac Mini works a little more.

 

 

I go still tried 5 types of filters and the new 2.5.0.7

 

 

THANKS A LOT DAMIEN AND MANSR!!!!

Conversion of PCM to DSD seems to be a no-go for me with the Mytek Stereo192-DSD. If I try to convert 24/192 to DSD128 (the max for the Mytek via FireWire), I get a very loud noise (sounds like 2 dissonant tones) for less than a second, followed by low-level white noise. This happens at both Level 0 and Level 4.

 

If I try to convert the same PCM track to DSD64, it sort of plays, but I get a couple of different medium-level tones periodically in the right channel (again, for less than a second) and the right channel seems to cut in and out, not to silence, but to a lower volume level and then back to the same level as the other channel. Pretty weird effect, but not as horrifying as the really loud noise I get when trying DSD128. Again, this happens at both Level 0 and Level 4.

 

Mytek is running the latest firmware.

 

BTW, is Level 0 supposed to be the lowest quality and Level 4 the highest?

 

Sorry to be a buzz kill.

My Audirvana 2.5.0.6 crash with ALAC files in 24/192 to DSD128.

[One and a half]

A0 Filter, FLAC 192 to DSD128 plays OK. CPU is 213%. Playing DSD64 -> DSD128 chews up 0.9% CPU. There's a stumble of 1/4s after the first track is played about 3s in, then it's fine for the whole album.

 

A3 sounds too distorted, a lot of flutter in the quieter passages, this is DSD64-DSD128, Mary Chapin Carpenter Time*Sex*Love Acoustic Sounds DSD download.

 

DAC = Sony PHA-3.

Does anybody know any alternate link for the download of the latest beta?

That does not work for me ...

 

Anyway, thanks a lot.

At least some of the filters in .7 should be better in that regard.

Link works fine for me, installed and up and running

 

Great work yet again Damien

 

Thank you

Works here - perhaps try to clear your browser cache, make sure the link address is correct....

Thanks for the kind words, but all credit goes to Damien and Mans.

I wonder, do you have a spinning drive inside your mini, or an SSD?

two SSDs 256 and 512gb

Note HQPlayer works fine temperature wise, only going into the low 70 while upsampling to 256. And HQP is very computer intensive on many of its mode settings.

I'm having some heat issue .... First 30 to. 50 seconds of every song the CPU temp rises to 93 to 95 deg C with internal fan blowing to the level I can hear it from my listening position, then temp drop to 52*C and fans slow to be silent?

HQPlayer is apparently better optimised for CPU efficiency.

Another overheating Mac Mini. Maybe they have inadequate cooling by design.

[Jud]

Would probably be helpful to see which filter options cause most CPU work with various computers.

Mansr, .07 update cured the problem. By using all four cores now it spreads the heat load out. Now it is about the same as HQP, low to mid 70s with the fan running around 4500rpm. Thanks guys.Great work.

 

PS, using A0 and B0 so far.
