For smooth real time audio it is necessary to zero out random jitter. Disable and circumvent CPU-threading for system and streamer.

If two threads correspond to a physical CPU, the CPU noise will also be separated. There would be two CPU situations for this configuration:

1. CPU SIX Core technology from ~10 years ago should be 3 physical CPUs; 2 can be dedicated to MPD daemon and 3 sacrificed;

2. 12-thread CPU technology from ~5 years ago with 6 physical CPUs declared (suspected mono CPU); 2 can be dedicated to MPD daemon and 3 dedicated to JACK daemon.

MPD makes much more sense to use just with ALSA for perfect, natural streaming. It would also make sense to lock CPU3 threading for the Linux/Liquorix module of USB-Host. When MPD and Jack are never used at the same time, they can both be locked to CPU2.

Would any system engineer have an idea and advice on how to implement the USB module lock?

Be careful that modern Pipewire technology, perhaps because it is an abstraction layer studied by audio beginners and laptop users, can only corrupt streaming perfection and limit playback to obsolete PCM. With Italian S.O. Seduzione Subersonica based on antiX23 is easy to disable/enable Pipewire. However, Jack(jackd) even corrupts the liquid state of the stream and this technique reduces the problem and improves the quality.

Virtual mastering certification and... state-of-the-art analog mastering process is only possible with PCM/DSD files via MPD or Squeezebox and ALSA (easy to install gnu/debian packages). Never with the DAW engine as it is only capable of pre-listening quality. Probably all sound engineers are ignorant about RT-Systems or are culturally & technologically criminals. The first to do extremely musical mastering are home studios with DIY converters and... Tempo Reale Linux/Liquorix.

In the past it was strictly necessary to remove the Pulse engine from the system to obtain ALSA streaming quality. At the moment Pulse is enabled and there is the problem that U-he DIVA still does not work at 768 kHz with Harrison Mixbus 32C. While before with AVL (antiX21) it worked divinely in divine mode at 32/768. But RT-IRQ and system also have a different setup. We will need to investigate or simply with this setup the proprietary nvidia video driver is required (for ethical and security reasons it should be avoided).

RT-IRQ prevents USB Kernel Module CPU migration for the stream. To achieve 100% physical isolation of CPU-streaming-noise, it would be delightful to find a method to block/isolate Streamer, Jack and USB module on the same physical core with this extreme low-random-jitter performance strategy.

Here is more info on S.O. S.S. https://electro-music.com/forum/post-455235.html

Furio Rupeni is the direct reincarnation of David Bowie who arrived one day before dying and manifested himself fully alive in the heart one day later... thanks to extreme implementation non-professional digital transport wolfson transceiver at 50ps jitter via TOSLINK-ISO by HiFiME & Output not active output stage with SOWTER insulators in pure Japanese copper (rame), RME HDSP9632, GNU/AVL/Liquorix... at the same time we were also testing the revolutionary opto-isolated digital transport JLSounds dot com & Buffalo USB-Host made in Japan /// you would never have expected the white duke or duca bianco /// nor had it ever interested you /// In a directory there is a 96 kHz Studio Master bought online in France and never listened to before the day after his death: The Next Day Extra /// is a completely distorted crappy master but it still opened up new dimensions and this new possibility. We are talking about myth number one... the disgusting, miserable life, physical disability, physical suffering of the last eight years... it's not explainable, a normal person would have died in the first month... but there was also sabotage with invisible secret substances (such as concentrated and modified crack and opium) and the physical suffering had also transformed into a apparent mental one with no mental illness...

Over the last month a strong feeling of love has inspired these three threads in the forum. Immediately after the snow event in spring (neve):

Brian Eno has released and announced a song made together 30 years ago. Who should be most interested in state-of-the-art recording, production and mastering? Over the last few days we've been urging Universal to get in touch, but nothing... Fuck Off!

* Those secret substances were already given when we registered in the forum. To initially attempt a strange manipulation with the Irish singer... as a collateral effect a university professor of electronic music in Rome had captured Ratzinger in the sum of our CGS Mixers and caused the papal abdication. So since I am Secret Secretary O.T.O.

if anyone can help to buy an Enterprise Hard Disk. In the ¨predyne" profile at instagram there would be some extreme eurorack VCAs for sale... or a very interesting DAP (flagship dual DAC) could be sold for the quality/price ratio 200 + 50 new minijack-RCA cable never used silver/copper OCC made with wondersolder and copper connectors & interesting factor is that with the mobile audio device... during the European football championships we made global capture (world wide) of all the enjoyment of the livestream viewers... With an investment of 700 euros in alcohol, but then we had to walk for 2 years with a cane due to "allergy" to toxic substances and chemical medicines.

** What if the Irish singing lady SOC had also been sabotaged with an identical chemical component and related electrical spiritual changes and forms in her brain? The strangest thing is that the DFA single... "Hello Steve Reich¨ and the Studio Master of THE NEXT DAY EXTRA disappeared from the market after db's death. Only a webshop sold it for a few years and then disappeared. Recently reappeared on the market split into two EPs. The media writes about the mastering of "MARS Magic Shop". So T.N.D.E & REALITY from the same studio. The two most distorted masters of db. Miserable loudness war.

The track Pablo Picasso (Japanese SACD ripped with PS3 transported/played via Mezzo Tera Sandisk SD) manifested a synchronization with the electronic engineer. So the energy was moved from HiFiME (ultimate vintage digital transport) to a secret British buffer bridge board for MCHstreamer, a temporary abandoned very powerful multi-channel I/O DSP development by Uwe Beis & JLSounds' I2SoverUSB.

*** The snapshot is taken from Instagram with blocked users like Brian E... David B... and someone else on Monday 22 April 2024 /// For Masonic reasons it would be written Italian, so "B. & D. Blocco Istantanea antiX23 Arditi del Popolo". Download 64 bit deep refernce Secure Recursive Spirit @ gnu/debian/arch/linux/liquoris (MPD & Jackd perform 32FP playback with alsa 24-32 bit... android is also a gnu/linux distribution).
