Hi there,
I observed some funny noise when Roon bundled with HQplayer upsampling certain format of files to DSD512.
I believe it is Roon’s problem in most case since I have done troubleshooting with Jussis from HQplayer and Jonas from NativeDSD already. Without Roon, using HQplayer upsampling these files alone won’t cause any funny noise issue.
My Setup
Operating System: windows 10 pro 64 bit
Roon version: Roon 1.3 (build 223) 64 bit
Device system: i7 3770, GTX 780, 32GB of ram size
Music stored: Tidal, and local hard driver
DAC: T+A DAC8 DSD
The issue
How does the funny noise sound like? Check the DJ-sound effect below.
Take this album for instance, Mendelssohn, Schumann: Violin Concertos Phantasy - Philippe Graffin
I have three versions in my Roon library.
- Tidal 44.1kHz 16bit
- DXD (PCM 352.8 kHz 24 bit) purchased from NativeDSD
- DSD 64 purchased from NativeDSD
1. When I use HQplayer upsampling DSD64 and 44.1kHz Tidal to DSD512.
HQplayer SDM setting:
filter: poly-sinc-xtr-2s,
modulator: AMSDM7 512+fs,
sampling rate: 48K*512,
auto family checked,
cuda offload checked,
mulicore DSP checked.
DirectSDM unchecked
Result:
I find there are some funny noise at the beginning of certain tracks. In this album (Mendelssohn & Schumann by Philippe Graffin), it’s 1st track (Allegro molto appassionato), 5th track (In kraftigem, nich zu schnellen tempo) and 6th track (Langsam).
I think you can easily hear the noise from Tidal streaming if you don’t have DSD64 file.
However, there is no such noise in the DXD version at all.
2. When I use HQplayer upsampling DXD, DSD64 and 44.1kHz Tidal to DSD256.
HQplayer SDM setting:
Filter: poly-sinc-xtr-2s,
Modulator: AMSDM7 512+fs,
Sampling rate: 48K*256,
auto family checked,
cuda offload checked,
multicore DSP checked.
DirectSDM unchecked
Result: There is no funny noise of all these three formats.
3. When I use HQplayer playback DSD64 with DirectSDM checked.
Result: There is no funny noise detected even in DSD64 file.
Furthermore, the audible noise still exist when Roon’s DSP engine is turned off.
I think there are some bridge issue or DSP engine conflict between Roon and HQplayer?
I also tried to do the same setup playback from other DSD64 files ripped from SACD. No such noise.
Please have a look and keep me updated.
Any help would be appreciated,
Wei
