I have a doubt, using the Mac with IOS I can use it without a problem until DSD128.
When I try to use DSD256 it works, but it fails.
I use the DAC of the Oppo 205 that goes up to DSD256.
I’m using a Mac mini I5 with 8GB of memory, an exclusive computer for audio.
Is this a problem with the processor or Audirvana?
Olá!
Tenho o mesmo problema. Você resolveu?
Sds.,
Olá
O problema é com o Oppo 205, com outros DACs funciona perfeitamente.
Olá!
O Audirvana deveria permitir no setup, baixar para DSD 128, como no Roon.
A solução foi desativar o DSD no setup do Audirvana. Reproduz 32/352.8kHz.
Sds.,
Stereo 2.8MHz DSD (DSD64) generates data rates as follows:
2 x 44100 x 64/8 = 705600 bytes per second
705600 x 60/1048576 = 40.375 megabytes (MB) per minute
705600 x 60 x 60/1048576/1024 = 2.3657 gigabytes (GB) per hour
Double this for 5.6MHz DSD (DSD128)
Quadruple this for 11.2MHz DSD (DSD256)
More RAM reduces CPU processing disc/RAM caching interrupts, thus reducing CPU processing = better performance.
RAM bus speed and disc/RAM caching is always going to be a factor in CPU processing overhead… The playback buffer is the key and how this is managed… if the I/O bus of the playback buffer is anemic this would cause playback anomalies… System operation must be unencumbered by disc/RAM caching and the Audirvana engine must be unencumbered by disc/RAM caching, so to maintain data integrity by reducing clocking related jitter due to buffer under-runs for best sound-quality and playback operation… There is a balancing act with the available RAM, bus speed and the bit-depth and sample-rate and length of the file being played, and any DSP being implemented in the player engine/system
May be a signaling issue over your network to the Oppo? Does the Oppo play DSD256 with direct USB?
Yes, Oppo plays DoP DSD256 directly on USB.
The problem is that it has small glitches during music.
With DoP DSD128 works perfectly.
