Seven selectable filter button, FIR:0 linear phase fast rolloff, 1: linear phase slow rolloff, 2: minimum phase fast rolloff, 3 : minimum phase slow rolloff, 4: apodizing fast rolloff(default), 6:corrected minimum phase fast rolloff, 7: brick wall filterġ) Connect the USB cable, turn on the power switch, the OLED display light up, and it can be used immedately.Ģ) The differential output directly from the DAC chip is labelled and connected to 2.54mm spacing socket for diyer easily connecting to their favorite IV and LPF(i.e.bypass the default onboard one).10 layer PCB (4+4+2), digital and analog part are carefully separated.Thin film resistor, six low noise linear regulator.
#Bitperfect sound in windows 10 install#
The golden knob can be pull out easily if the user have their customized case when install the front panelĪll buyer of the fullly assembly Audio DAC can enjoy 2 month free* try! This item is fully assembly and fine tuned, we have confidence you will like it.Ĭonditions: (no physical damage/modification, the item must be the same outlook as it was received, user is responsible for the return shipping fee and USD30 administration fee. Audiophile can enjoy their favourite music from the computer immediately. This is the first fully assembly Audio DAC from us. So I mean Windows mixer was completely bypassed from the path.(If the dual mono DAC PCB is not used with the bundled xmos PCB, external MCU is needed to set each DAC chip register to left and right channel operation) I also found that setting sample rate in device properties had no effect on sound and I always got DSD128 no matter which sample rate was set. So it is clear the sound went through Windows Mixer - despite the fact that volume setting has no effect.Ģ) When Virtual Audio Cable (KS) appeared at front of the chain as default audio device I observed better sound (better trebles, more air. I had also some dropouts on higher sample rate settings. It seems that foo_dsd_asio is capable of doing PCM to DSD conversion only for multiples of 44.1k. When I set multiples of 44.1k, DSD128 is shown on my DAC and when I set multiples of 48k, PCM sample rate is shown - no PCM to DSD conversion is done by foo_dsd_asio ASIO proxy. But I found some differences against adding Virtual Audio Cable (Kernel Streaming) at front.ġ) When Virtual Audio Cable was not used and VB Hifi Cable was set as default audio device, I found that sample rate setting in device properties Advanced tab (you call it Windows Mixer) has influence. You are right that device volume setting has no influence. Yes I tried to set VB HiFi Cable as default output device and it functions with ASIO Bridge. Can you see if you still get DSD without Virtual Audio Cable? Since I posted I tried VB Audio Hifi Cable and got it to act so the Windows mixer audio volume control has no effect, leading me to believe that VB Aufio Hifi Cable bypasses the Windows audio stack. These ASIO proxies allow to perform some digital signal processing before audio is sent to DAC.Īny reason not to just use VB Audio Hifi Cable from Windows Mixer out to foo_dsd_asio or Asio4All for that matter? I used foo_dsd_asio from Maxim Anisiutkin, but also JRiver Media Center ASIO device could be used. It means it is possible to pass bitperfect Windows audio from any Windows application to any ASIO device, including special ASIO proxies. Now I am playing video with 44.1k audio in Windows Media Player, my DAC control panel app shows 352800 (that's DoP sample rate corresponding to DSD128) and my DAC display shows DSD128. VB Audio HiFi cable and ASIO bridge from VB-Audio Virtual Apps Virtual Audio Cable as vladimirb0b suggested in OP I reached it by passing default output audio device to foo_dsd_asio ASIO proxy. I found a way to get DSD128 output from any Windows application (DSD128 is max. I got the idea to get things yet more complicated and to reach yet more!
