AudioLinux is based on realtime custom kernels and on the work of that part of linux community trying to achieve very low audio and processor latencies. The results are not audiophile subjective suggestions, but real and measurable. No magic hidden code, but only the magic of music. AudioLinux can be used in Audio Pro studio recording because of stability and freedom from glitches. With a powerful CPU is perfect for extreme upsampling (up to DSD1024  or PCM 1536 kHz). What about the sound? Clean, transparent, the last veil is removed... and a quick and complete support that no one is giving in Linux. Your system will be fine-tuned for the absolute best performance.

Why should you buy Audiolinux?

1) Audiolinux kernel with the realtime patch will give audio applications a very high priority with record CPU latency that can arrive at less than 1 microsecond average on some systems

2) Audiolinux V3/V4 kernels are compiled with x86_64_v3/ x86_64_v4 architecture, LTO FULL, 2000 Hz frequency and many patches including Audiolinux ones for a performance uplift from 10% to 36%!
Moreover pre-compiled optimized kernels are available for many architectures. If your CPU is not on the list you can ask support for a new optimized kernel that after will be updated regularly or you can compile the kernel automatically yourself

3) In V3/V4 versions applications and libraries are compiled with x86_64_v3/x86_64_v4 architecture

4) The proprietary application RTPRIORITY can assign specific realtime priority to your audiocard, audio application and network (rtirqs, rtapp, rtnet)

5) With proprietary application PPOWER you can choose and configure your CPU governor driver: acpi, intel pstate, amd pstate or amd pstate epp

6) A menu with more than 120 options with which even a system without a graphical desktop is easy to use

7) With ramroot option you can load the entire system to RAM for a record reactivity and general performance. This way you can run a system without drives

8) Full access to root will allow to install all applications available on linux and apply special configurations

9) Fast email support and remote Desktop support with AnyDesk if necessary

10) You can access Audiolinux from another PC with ssh/sftp, Web interface from a browser and NoMachine remoteDesktop in lxqt version

Audiolinux versions

Audiolinux classic headless is without graphical Desktop but a full set of menus. A little better in performance because of less memory used and less processes active

Audiolinux classic lxqt is with graphical LXQt Desktop and all audio applications already installed and tested. Audiolinux menus are included

Audiolinux headless and LXQt V3/V4 are completely rebuild OS with most applications and libraries compiled with x86_64_v3 or x86_64_v4 and LTO with kernel optimized for your specific CPU

Audiolinux V4 headless 7.4.0
Audiolinux V4 lxqt  9.4.1 NEW!

AUDIOLINUX MINI GUIDE

(clik on images for full size display)

Main menu
Audio menuAudio  extra menuSystem menuStatus menuExpert menuInstall/Update menu
 INSTALLATION

--> You cannot install Audiolinux on a single partition but only to the full hard disk (Audiolinux image has 2 partitions, UEFI fat32 and linux ext4). The target drive will be deleted. Recommended minimum size is 32 GB.
We recommend to install Audiolinux first to USB stick and after copy the installation to internal drive with the option "COPY/BACKUP current installation to another drive" in System menu. Keep this USB installation, it will be useful if you want to install to a second PC or for emergency fix.

LINUX
To install audiolinux on external USB stick or internal Hard Disk, if you already have linux installed  (-> change name to your version file name):

1) Boot from your linux installation and download the image

2) Verify that the image file is not corrupted with
sha256sum audiolinux_mini_740.img.gz

3) Find the hard disk address by typing
sudo fdisk -l

4) If, for example, the HD is /dev/sda, copy the image with
gunzip -c audiolinux_mini_740.img.gz | sudo dd of=/dev/sda bs=1M status=progress
(this will delete the hd, it is not necessary to format it previously)
/run/media/audiolinux/audiolinux_rpi4/boot/
5) Extend the ext4 partition until covering the remaining part of the hard disk (this will fix also GPT size errors. Note that you will need more than the default size for Roon database)
--> If you plan to use ramroot later, leave some unallocated space on the hdd for an extra partition or add another drive, otherwise, if you copy the music files into audiolinux partition, the size will become too big for booting to ram.

6) Power off the PC, unplug previous external linux installation and boot from the new HD/USB stick.

WINDOWS
If you install from Windows, you can use Rufus version 2.18 with option "dd"

MAC
If you install from MAC, see the guide here or you can use Etcher

HOW TO RESIZE AUDIOLINUX PARTITION
a) If you have Audiolinux LXQt: make a second installation on a USB stick, boot from the new installation and extend the ext4 partition on the old installation with gparted (easy, because the application has a GUI)
b) If you don't have Audiolinux LXQt: enable ramroot, reboot, select the option resize in system menu.
If you want to switch back to normal mode: reboot answering N to ramroot boot prompt at the beginning of boot, disable ramroot, reboot

--> If you have problems booting, consult our Booting Checklist

This is the official how-to, You can use also other methods that allow the cloning of an image with multiple partitions.

You can use Audiolinux for audio in the following combinations (but you can install all applications available for linux, since you will have full access to the OS)

1) HQPlayer embedded controlled by HQPlayer client or Jriver or HQPDcontrol, BubbleUPnP, Mconnect on smartphone/tablet
2) HQPlayer Desktop (lxqt version)
3) Roon
4) Roon wth HQPlayer Desktop or HQPlayer embedded
7) MPD controlled by Cantata  or many other control points on smartphone/tablet if you enable UPnP for MPD
8) Logitech Media Server (LMS) and Squeezelite. Many control points on smartphone/tablet available
9) Jriver Media Center (lxqt version only)
10) Spotify with the audio sevice raspotify, controlled by
official Spotify on smartphone/tablet/PC
11) NEW! Audirvana Studio or Origin controlled by remote Audirvana app

Tidal and Qobuz music streaming services are already integrated in HQPlayer client,  Roon, LMS, Audirvana, BubbleUPnP and Mconnect.

The option '21 MPD+JACK enable/disable' will now start and stop automatically jack
The option '2 - MPD: start with jack native' in Jack configuration will start both jack and mpd-jack

When running audio services shows more than one application using RTAPP, the following explanation has been added:
'Real priority could be different if more than one application is using RTAPP
In that case check REALTIME status in STATUS menu after 60s
RTAPP is decreasing priority following the order of APPS_DEFAULT applications with a step defined by PRIORITY_STEP in /etc/rtpriority/rtapp.conf to avoid 2 or more services with the same priority value'

Some improvements in Jack configuration script
Added 'Not compatible with Diretta and Ravenna'
Menu 835
Improved JACK option in Audio extra menu (only Audiolinux lxqt)
The advantage of using Jack is that you can add a VST plugin at the output of your player

1) If you want to use MPD with native Jack, configure MPD and start Jack with option 2 - MPD: start jack native, go to Audio menu and select 21 'MPD+JACK enable/disable (VST plugin compatible) *'

2) If you want to use another player (for example HQPlayer), enable Loopback device with option 1 - LOOPBACK enable, start Jack with option 3 - ALL OTHER PLAYERS: start jack plugin, configure your player output to looback device 0,0

*** Only PCM supported ***
*** There is not sampling frequency auto-switching, you must set you player to the same frequency defined for Jack ***

3) For installing VST plugins, see this Archlinux wiki page: https://wiki.archlinux.org/title/Audio_plugins_package_guidelines
Start Carla from Application menu in Audiolinux lxqt, add a plugin, select Patchbay tab and make these connections:
Canvas -> Show external:
Music Player Daemon or cloop -> Carla input -> Carla output -> system
Canvas -> Show internal:
Audio input -> VST plugin input -> VST plugin output -> Audio output

Some images of Carla configuration can be found here: https://www.audio-linux.com/ftp/temp/Carla/

Finally you could save your Carla configuration for example to /home/audiolinux/carla.carxp.and add the line
carla /home/audiolinux/carla.carxp
to Autostart in lxqt configuration

-> For realtime priority the value should increase this way:
MPD -> Jack -> IRQ
that is Jack priority must always be higher than player priority
-> Your previous /etc/jack/jack.conf will be saved as /home/audiolinux/Downloads/jack.conf.bak
-> For more information about JACK Audio Connection Kit go to https://jackaudio.org/
Menu 834
Added new option 21 'MPD+JACK enable/disable (VST plugin compatible) *' in Audio menu
Added new option 12 'MPD+JACK configuration' in Audio extra menu
The advantage of using MPD+Jack is that you can add a VST plugin at the output of MPD
In Audiolinux lxqt you could install Carla with
sudo pacman -Sy carla
and install some VST plugins, see this Archlinux wiki page: https://wiki.archlinux.org/title/Audio_plugins_package_guidelines
After start Carla, add a plugin and use the patchbay to make the connections:
MPD -> Carla input -> VST plugin -> Carla output-> Jack
For realtime priority the value should increase this way:
MPD -> Jack -> IRQ

Correction to EXTREME2: All but POLL only isolated cores in System menu -> BOOT mode to Extreme, Extreme2, Standard or Adaptative
'Do you want to apply to all isolated cores or to a subset?
For example if isolated cores are 2 3 4 5 and you want to apply extreme(2) c-state only to 2 3 4 you should type 2 3 4
Otherwise type y'
Menu 823
Now you can select which isolated cores you want to set to extreme(2) in System menu -> BOOT mode to Extreme, Extreme2, Standard or Adaptative -> EXTREME2: All but POLL only isolated cores (EXTREME: All but POLL/C1 only isolated cores)
Added 'Do you want to apply to all isolated cores a to a subset?
For example if isolated cores are 2,3,4,5 and you want to apply extreme(2) c-state only to 2,3,4 you should type 2,3,4
(probably not a good idea to set an extreme c-state to the core where you have isolated network irq)
Otherwise type y'

Added a delay of 30s to the isolated_app systemd service
This could solve the problem that network irqs were not isolated because network was not fully established after a (re)boot
You can increase the value editing as root /etc/systemd/system/isolated_app.service
Released Audiolinux Raspberry 4.4.0 with menu 425 and kernel 6.12.6
Menu 425 Raspberry
