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 interfaces 1 or 2 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 are completely rebuild OS with most applications and libraries compiled with x86_64_v3 and LTO and kernel optimized for your specific CPU
The x86-64-v3 level enables AVX, AVX2, BMI2, MOVBE, XSAVE, and other instructions found on Intel and AMD processors of the past several years: Haswell CPUs and newer and AMD Excavator and newer

AUDIOLINUX MINI GUIDE

(clik on images for full size display)

Main menu
Audio menuAudio  extra menuSystem menuStatus menuInstall/Update menuExpert 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_580.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_580.img.gz | sudo dd of=/dev/sda bs=1M status=progress
(this will delete the hd, it is not necessary to format it previously)

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 spotifyd, controlled by
official Spotify on smartphone/tablet/PC

Roon with HQPlayer

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

AudioLinux CPU latency test

We have made some tests of the real performance of AudioLinux.
You can make a similar test yourself selecting Realtime test in Audiolinux Status menu.

1) Test on Audiolinux lxqt with Ryzen 5800X

Audiolinux latency test

2) A test with the same computer in Windows 11 with DPC Latency Checker

Win11 latency


Audiolinux testing system

Ryzen 5800X server, Intel i7 Fanless PC in a Streacom case as endpoint, Holo Audio Spring Dac,  custom tube preamplifier, custom Hypex power amplifier, modified Audiostatic electrostatic speakers DCI A-sinus. This system, with Focusrite mic preamplifier, is used also for audio recording/monitor.
