Download, start and test LibraZiK-3 in live
(Version française / French version)


You can try LibraZiK-3 without installing anything on your computer. All you need is a USB stick of at least 4 GB or a DVD.

The following procedure will explain how to make a live of the “LibraZiK-3 Audio Studio”. This is done in a few steps:

  • first, you will need to grab an ISO image of the LibraZiK-3 live.
  • secondly, you will have to write it on a USB key or to burn it on a DVD.
  • then you will be able to boot on it and to try it out.
If the experience convinces you, you can then choose to install LibraZiK-3 to enjoy better performance than the “live” of LibraZiK-3, which does not offer the same performance as a classic use with installation on a hard disk. However, this LibraZiK-3 “live” allows you to test a lot of things and get an idea before installing.
The use of a LibraZiK live in a Virtual Machine 1) is not recommended because the management of audio devices, audio, and real time are very often far from being correct for use in a audio production context.

Get an ISO image of the LibraZiK-3 live

The ISO images contain a functional LibraZiK-3 system as well as a wide selection of free and open source software dedicated to music production.

Go to : and download the librazik3-20201104-en-amd64.iso file for a 64bits version in English. Once downloaded, you will be able to check the ISO integrity thanks to its MD5sum Checksum which must be c21b8b0803f27afd71e7563daa729991.

Checking under linux®

Once the ISO image has been downloaded, open a terminal and go to the directory where the downloaded ISO image is located: cd /path/to/folder. Now use the command (replacing file.iso by the full name of the ISO file downloaded in the previous paragraph): md5sum file.iso, which should return a checksum. You just have to compare it with the checksum given above.

The calculation of this sum with the above-mentioned command can take several tens of seconds or even a few minutes, depending on the capacity of your machine.

USB or DVD ?

It is possible, if your machine supports it :

  • either to write the ISO image on a USB key and to boot from it,
  • or to burn the ISO image to a DVD and to boot from this DVD.

Booting and using from a USB stick is, most of the time, faster than from a DVD and therefore, if your machine offers you these 2 possibilities, it is advisable here to go for the USB stick. If you use a USB key here, it is advisable to delete the files on it, then format it in “FAT32” before putting the ISO image on it.

Please keep in mind that in both cases, this possibility of booting (by USB key or DVD) without installation allows you to get an idea of the system, but a system installed on a hard disk will be even faster and more functional.

The creation of a live LibraZiK-3 is not possible on CD because the ISO image is larger than 700M (it is 3.3GB). If you have a machine with a CD drive only, you will not be able to try LibraZiK-3 in this way. However, you will be able to consult the different installation methods.
If you choose a “slow” media such as a DVD for example, it is likely that the system and software running on this media will be slowed down, and even might be really unusable. Don't assume that LibraZiK-3 is unusable too!

ISO inscription on a USB key

If you got for a USB key, choose one of the following methods.

Writing the ISO on a USB stick can take several minutes and does not display anything on your screen. It may therefore appear that nothing is happening when in fact it is. Be patient, and leave your machine running. If after half an hour, the command remains “stuck”, then it is time to try again, or even to think about trying with another USB key.

Writing on USB key under Linux® (general)

Please be aware that everything on your USB stick will be destroyed - so be sure :
  • of the target partition to target,
  • to have saved what was on your key.
  1. In a terminal, run the command: watch "dmesg |tail".
  2. Then plug your USB key into your computer, you will see the inscriptions in this terminal change. It is your linux® kernel which is telling you that it is discovering a new peripheral and what it does with it.
  3. Find out where your USB key is located. For example : sdb: sdb1.
  4. Then, in another terminal tab (do: Terminal menu → File → Open a tab ), the magic command to write the ISO on the USB key to make it a bootable USB key is: su -c "cp /path/to/your/file.iso /dev/sdX" with replacing the “X” in /dev/sdX by the letter corresponding to the location of your USB key (in the example above: /dev/sdb)
  5. Once the copy has been made and when the terminal gives you the hand back, run the sync command to make sure that everything is properly written on the key and that there is nothing more being written to the key caches.
  6. Unmount your key cleanly.
  7. Close the terminal window.
  8. Your USB key is ready.
The ISO image should be copied to the entire device, not to one of its partitions.The ISO image should be copied to the entire device, not to one of its partitions..
Example: /dev/sdb and not /dev/sdb1.

Writing on a multi-boot Live USB key

It has been reported (in French) that the use of LiveUSB was functional.

Writing on USB key under Ubuntu® Linux®.

Method 1: General

Same method as above, simply replace the command:
su -c "cp /path/to/file.iso /dev/sdX"
by :
sudo bash -c "cp /path/to/file.iso /dev/sdX"
or, if this one doesn't work:
sudo dd if=/path/to/file.iso of=/dev/sdX

Method 2: usb-creator-gtk

It has been reported by a user (Didier - thank you!) that with the “Ubuntu 16.04 Mate Alpha” version, the use of the “Ubuntu usb key creator” 2) made it possible to create a key.

Method 3: Use of unetbootin

It has been reported by a user (Didier - thank you!) that: “after downloading, I created a Live Usb key with Unetbootin and then launched it on a computer type i7-2600”. So it seems to work as well. That said, there may be some problems: bug 775689 at Debian. See also this tutorial.

Method 4: Using mkusb

It was reported by a user (Louis - thank you!) that it was also possible to create a USB stick bootable under Ubuntu with mkusb (see also this explanation).

Writing on a USB key under Windows®.

There are several possibilities. Five of them are proposed below.

Possibilities tested and approved with LibraZiK-3:

  1. A solution is the use of Rufus (confirmed by N-i-c-o on IRC with Rufus 3.12)

Possibilities tested and approved (with the old LibraZiK-2 version):

  1. One solution is to use Linux Live USB creator. 3)
  2. The utility win32diskimager works for that.A tutorial is here. Please note that you will need to put *.* instead of *.img when searching for a file.

Possibilities not yet tested/approved :

Please note that so far LibraZiK-3 has not had any feedback about the following different methods so if you try one and it works, please come and let us know by contacting us.
  1. Yet another solution is to use unetbootin for Windows. See also this tutorial.
  2. A last one is: USB-Writer. See also this tutorial.

Writing on USB key under MacOSX®.

Please note that so far LibraZiK-3 has not had any feedback about the following method so if you try it and it works, please come and let us know by contacting us.

Burn ISO to DVD

If you go for a DVD, use your usual software.

Start on, and try LibraZiK-3

From there, you will be able to try LibraZiK-3 without installing anything on your hard disk for the moment. To do this, simply plug the USB key into one of the computer USB ports 4) and then start the machine. Of course, your computer must be hardware capable of booting on a USB 5) 6).

On some computers, the possibility of booting from the USB key 7) must be configured in the BIOS. 8).

After this step, you will arrive on another step : LibraZiK-3 : first startup screen

Here you will choose “Live (amd64)” by selecting it with the keyboard arrows and then pressing ↵ Enter.

You will then wait a little while and you will arrive on the LibraZiK-3 live desktop. A large selection of LibraZiK-3 supported software is pre-installed.

To access it, go to the top menu → Applications → Sound and video → ….

Notes concerning the use of LibraZiK-3 in "live" mode

You can install software from the repositories. However, if you launch an installation from the same live session, the software that you manually installed in the live session will not be hard installed. You will have to install them again, once you have restarted on your hard disk installation.

In case you need it, the login/password of the “live” is: user/live.

Also note that in “live” mode, sudo is used to access super user functions.

In the case of a DVD, using a live can be really slow, this being due among other things to the rotation speed of the DVD and the reactivity of your machine. The same is true for some USB flash drives of poor quality or at the end of their life..

you can check this in your machine's documentation
The BIOS configuration is usually accessible by pressing a key on the keyboard such as F2, F12, Delete or Escap when booting the machine. As this depends very much on your machine, it is impossible to list here exactly which command to use to enter the BIOS for each machine. Please refer to your computer manual and also note that the key to be pressed is often mentioned on the screen during the very first seconds of the computer's boot
