STC Posted November 23, 2019 Share Posted November 23, 2019 My normal usage for playing stereo is usually around 5%. And going full convolution DSP it would hit 100%. Except for some drop outs at 100% I do not hear any difference to the sound quality. The original sound was recorded in DAW and the file is very large. It is available on request. The sound in the video is from the phone and the changes you hear is due to my movement and not due to the load.

PeterSt Posted November 23, 2019 Share Posted November 23, 2019 If you don't perceive differences, then your system must be way under par. Let's not forget that XXHighEnd is all (100%) about this, and the differences are huge (by means of countless settings combinations). Btw, the CPU load is a virtual 0% at 32/768 (16x upsampling from Redbook in real time). sandyk 1 Lush^3-e Lush^2 Blaxius^2.5 Ethernet^3 HDMI^2 XLR^2 XXHighEnd (developer) Phasure NOS1 24/768 Async USB DAC (manufacturer) Phasure Mach III Audio PC with Linear PSU (manufacturer) Orelino & Orelo MKII Speakers (designer/supplier) Link to comment
PeterSt Posted November 23, 2019 Share Posted November 23, 2019 PS: I could have said that a tad nicer. So apologies. But it also seems blunt to just say that you are wrong or something. So there must be a reason, which net (!) comes down to what you perceive from it. Btw, any processing (like DSP stuff) tends to kill the nuances, so there is reason #1, but it wasn't clear to me whether you are using that in this "test". Obviously with your Ambio stuff you will be using that, so ... Anyway, constructively meant. But why did you come up with this in the first place ? PPS: I can't get the video to play ...

STC Posted November 23, 2019 Author Share Posted November 23, 2019 Firstly, that was a stereo file. The PC was running normal processes of all the ones associated with Windows10 including Firewall. The network is activated. So too the anti virus. And ACDSee is running in the background. For serious listening all the processes will be killed and if I remember correctly it will be 1% with just JRiver. It is probably 5% because the data is linked to DAW via virtual cable. That would have added the load. Thankfully the cheap system somehow not degrading further despite CPU reaches 99%. Sorry I didn’t know this is what XXhighender is all about.

With previous versions of Windows I obtained a worthwhile improvement by running Windows in Safe Mode, which reduces the number of background processes running, as well as prevents non essential programs from starting. However, Windows 10 is a P.I.T.A. to do this.. Fidelizer by Windows X does similar with Windows 10 as well. If I wanted to create a poorer sounding audio file for comparison purposes I also ran a full Security scan at the same time. Even unplugging or switching off the cable to the Broadband Router resulted in a small but worthwhile improvement with Audio. Alex How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area. All that Identical Checksums gives is the possibility of REGENERATING the file to close to that of the original file. PROFILE UPDATED 13-11-2020 Link to comment

Hopefully, one can handle twice the load so that I could utilize all the IRs. Maybe then I will probably concentrate on other tweaks. Frankly, I don’t see there is a need to limit a PC’s usage. These minor tweaks becomes immaterial for my setup. Not to say they won’t make a difference but those difference are not important when considering other errors.

My PC only uses an i7 -3770 CPU @ 3.4GHz with a 600W SMPS . (I also have an internal Asus Video card, and an internal Asus Xonar D2X Soundcard) However , I use additional; very low noise regulated +5V supplies for the 2 internal SSDs derived from the +12V rail of the PC. I also have 2 internal HDDs in this general purpose W10/64 P.C. The Audio side is catered for by using coax SPDIF from the Asus Xonar D2X to a highly modified Musical Fidelity X-DAC V3.

Killing unwanted processes started in early days of computers with limited CPU and RAM. This started with gamers. Audiophiles thought the same must be true and maybe some entry level PC would have benefited by turning off unnecessary processes although I suspect it got more to do with the reason Mansr stated as audio takes very little CPU load to play music without DSP. I hear differently than most audiophiles but it doesn’t mean I am incapable of hearing differences. It is just I don’t hear things that audiophiles often make but couldn’t prove. In my example, I could capture the output digitally and the 24/96 files should show the difference. pkane2001 1 ST My Ambiophonics System with Virtual Concert Hall Ambience Link to comment

Other programs such as Ashampoo Win Optimiser also provide these kinds of facilities which also improves system response times , as does Norton Internet Security. You probably can't hear differences between files saved on different storage media either, when playing from System Memory either, however many members are able to, as evidenced in Rajiv's massive thread in Music Servers where quite a few members are now even reporting an improvement in SQ when using higher quality (expensive!) wider temperature range System Memory.

Your hero Archimago is NOT infallible either. Sighted listening is meaningless as proof of anything in audio. The most elementary understanding of human perception shows that. You can believe whatever you want. Going from your sighted listening to saying you've proved something is just belief in voodoo. Didn't say Archi was infallible. Can you show his measurements are wrong? If high CPU rates, etc don't increase distortion, noise, jitter etc., what is the cause and effect of what you claim you hear?
