I use DAYTON AUDIO UMM-6 which is a USB microphone.
Before, I believed them too much and set the delay compensation value directly based on them. I never suspected it was wrong before using the method you shared.
Can your system play CSGO? This game supports 5.1.
Heheh. I am a first person shooter aficionado but CSGO is a gong show for me. It's nuts! I like more stealthy stuff.Even though I assume that I may configure my multichannel system for playing PC games support 7.5 and/or 5.1 surround audio, I have little interest on PC games.
So far, and also at present and in future, my multichannel multi-driver multi-way multi-amplifier stereo system is dedicating for pure HiFi stereo music listening.
Same here, I listen to music on my 5.2.4 system at least 3-4 hours a day. On the other hand I may watch one movie every couple weeks or so, the largest part of which are Sci-Fi or Action-Adventure flicks.So far, and also at present and in future, my multichannel multi-driver multi-way multi-amplifier stereo system is dedicating for pure HiFi stereo music listening.
Hello @dualazmak san,Again, "Near ultrasound - ultrasound" ultra-high frequency (UHF) noises in HiRes music tracks, and EKIO's XO-EQ configuration to cut-off such noises
I rather intensively investigated and shared this topic and my counter measure; "Near ultrasound - ultrasound" ultra-high frequency (UHF) noises in HiRes music tracks, in my posts #362-#386.
Although quite belated, today I noticed this important and interesting thread;
SOUND LIAISON, PCM DXD DSD free compare formats sampler. A new 2.0 version.
where Sound Liaison generously described about sharing "free compare formats sampler. A new 2.0 version" for which they wrote that "We tried (and succeeded quite well) in recreating the sound the analogue vintage equipment added to the voice by using the tools we have in our digital workstation. But now without added high frequency noise."
These "free compare formats sampler. A new 2.0 version" tracks were newly prepared by Sound Liaison after amirm's specific post and amirm's YouTube video clip on Sound Liaison's original "compare formats sampler (1.0 version)".
Today I shared the following information in my post here on the interesting remote thread entitled "DSD is better than PCM!", and I do hope it would be allowed to share also in my project thread here, since the topic and information are still closely related to my system setup and configuration.
Now, I am just very much interested in "quality control, QC" of these "SOUND LIAISON free compare formats sampler 2.0 version", I quickly analyzed them by using MusicScope 2.1.0, as follows;

View attachment 185616
We may clearly see that these "version 2.0 compare formats sampler" tracks contain much less UHF (ultra high frequency) "noises" in comparison with their original version 1.0 tracks.
We can also find, however, that the HiRes format tracks still have "sound" or "noise" components beyond 25 kHz, I mean in 25 kHz to 176.4 kHz frequency area. Since I (we) can hear up to ca. 22 kHz, the "value" (and "meaning") of the sound over 30 kHz would be the subject of our further discussion.
At least in my latest audio system setup and configuration, PCM 88.2 kHz WAV or FLAC 88.2 kHz (up to 44.1 kHz in each of the L & R stereo channels) would be "sufficient" enough, since the digital XO/EQ "EKIO" can work up to 192 kHz 24 bit and also having protective -48 dB/Oct high-cut (low-pass) LR filters at 25 kHz to eliminate any UHF sound/noises over 30 kHz (please refer to my posts #362-#386).
Consequently, even though my digital music library (ca. 25,000 tracks) consists of so many formats of DSD (8x, 4x, 2x,1x) FLAC (44.1 kHz- 352.8 kHz) and WAV/AIFF (44.1 kHz - 196 kHz), now I usually set "JRiver's DSP studio" in 88.2 kHz output of all the music tracks stereo 2-channel (on-the-fly conversion) as well as I set EKIO in 88.2 kHz sampling rate.
The simple reason for my current choice of 88.2 kHz, instead of 96 kHz, is that majority of the tracks in my music library is CD ripped non-compressed 44.1 kHz 16 bit AIFF format. As for my music library organization strategy and policy, you would please refer to my post here in a remote thread.
And, I should not forget about sharing the important subjective impression that all of the 15 tracks in "SOUND LIAISON, PCM DXD DSD free compare formats sampler. A new 2.0 version" sound really amazingly nice!
Hello @dualazmak san,
thank you so much for sharing this monumental project.
I read all of your thread, but I guess I will have to go back to it many times before I can truly understand in full all the details inside it.
I would have a tonne of questions, but most of them are due to my ignorance and it is much better if I dig around the net to fill my gaps.
One thing I did not understand about the way you play your music: do you feed the music files to the DAC in the same format they originally come (PCM/DSD) or do you let JRiver MC do the conversion before sending data to the DAC?
I am asking because a post on mojo-audio.com (https://www.mojo-audio.com/blog/dsd-vs-pcm-myth-vs-truth/) strongly, very strongly, suggests feeding each DAC chip its 'native' format (just a few paragraphs before the summary you can find the reasoning behind the suggestion).
Maybe with the Sound Liaison, PCM DXD DSD... you could really tell if mojo-audio advice is really correct.
Hope this is not a redundant question and may help somehow in the quest for a great audio experience.
Thank you very much again for sharing all your efforts.
Thank you very much @dualazmak san for your detailed answer.Hello @adLuke san,
Welcome to this project thread! Your above inquiry is nice and important point, indeed.
My present answer for you is "It is quite feasible enough and even ""needed"" to feed all the audio digital signals in 88.2 kHz or 96 kHz PCM (or 192 kHz, if you like) by JRiver's on-the-fly format conversion to be sent into DSP (XO/EQ) software EKIO. "
Various background and justifications for this answer are as follows;
Before starting this project, I had been enjoying music with ordinary PC audio setup with one DAC (OPPO Sonica DAC)) and one HiFi integrated amplifier (ACCUPHASE E-460) driving all the SPs through passive LC (inductors capacitors resistors) network. And I had been sticking to "native format feed" into OPPO Sonica DAC up to 1-bit/DSD256(4x), as you kindly pointed.
When I started considering possible multichannel multi-driver multi-way multi-amplifier project with software DSP (XO/EQ), I did intensive search and desk evaluations on various DSP software solutions, and I found the maximum PCM processing format is 192 kHz 24 bit in these DSP software solutions. (Even with the extraordinary expensive TRINNOV ALTITUDE 32 DSP processor, actually having PC in it, the internal DSP processing is up to 192 kHz).
I carefully considered the pros and cons of "DSP processing all tracks in 192 kHz or 96kHz" instead of "native format feed", and concluded that multichannel multi-amplifier approach would surpass the cons, at least in my system setup with still amazingly wonderful Yamaha SP drivers and cabinet.
Consequently, I decided to go into "multichannel multi-amplifier" world of "max. 192 kHz 24 bit processing", as you kindly have read through this project, including the "all in max. 192 kHz ASIO I/O within PC".
Then, rather recently, I (we) fully discussed and evaluated the UHF (ultra-high frequency) noise issue in poorly QC-ed HiRes music tracks including DSD formats, as you clearly noticed;
- "Near ultrasound - ultrasound" ultra-high frequency (UHF) noises in improperly engineered/processed HiRes music tracks, and EKIO's XO-EQ configuration to cut-off such noises: #362-#386, #518
I wrote that such a high amount of UHF noises would be "possibly" harmful (and useless, meaningless) for our tweeters and super tweeters. I also pointed they would be highly possibly harmful for our beloved pets including dogs, cats, birds.
Having my intensive objective measurements of these "poorly QC-ed" HiRes tracks, and having so many intensive discussions on "enough PCM bit rate in HiFi audio", now I conclude that 88.2 kHz or 96 kHz processing (i.e. up to 44.1 kHz or 48 kHz in L and R channels) would be just enough and feasible in my setup (and I believe so also in your setup) since I decided always having high-cut (low-pass) -48 dB/Oct filters at 25 kHz in my EKIO configuration to cut-off any of the possible UHF noises very frequently existing in HiRes tracks.
This means that I have finally landed on agreement with @mikessi's "enlightenment and belief" of "There is really no audible benefit to playback beyond 24/96 sampling, especially with any recordings other that those done with the most advanced high res gear and high fidelity values."
Another important aspect of this issue would be relating to our hearing ability in high frequency zones. Recently, I participated in a interesting thread entitled "Audio Listening With Age Diminished Hearing". You would please read my posts #70, #72 and #74 on that thread.
BTW, as I wrote here, here and here, my digital music library of about 25,000 files consists of mixture of various formats;
16-bit/44.1kHz CD ripped non-compressed aif (majority!),
24-bit/192kHz down-sampled or up-sampled aif,
1-bit/DSD64(1x) 2.8MHz dsf,
1-bit/DSD128(2x) 5.6 MHz dsf,
1-bit/DSD256(4x) 11.2 MHz dsf,
and now JRiver MC feeds all of the tracks usually (mainly) in 88.2 kHz 24 bit (i.e. max. 44.1 kHz Fq window in 2-ch stereo) by on-the-fly conversion into EKIO for crossover/EQ processing. As I have high-cut (low-pass) -48 dB/Oct LR filters at 25 kHz, max. 44.1 kHz in L & R channels are more than enough.
So this would mean that JRiver should convert first all the flac and aif files to dsf format on the fly before feeding the DAC.
