![]() Windows/Mac equivalent: EZ Drummer, Reason When audio is recording and playing back as it's supposed to, connecting other applications that can provide drum machines etc could be useful. Second step - Connecting applications through JACK Once installed, it will be found under Applications -> Sound & Video -> Ardour GTK2.Īrdour requires a JACK daemon to be running when it starts, so be sure it's started from the previous step. To install, enter that convenient terminal and issue: sudo apt-get install ardour It is the central place for music production in Ubuntu Studio. You can use it to record, edit and mix multi-track audio. Windows/Mac equivalent: Cubase, Logic, GarageBandĪrdour ( ) is a Digital Audio Workstation. Once the basic configuration is done, start the JACK daemon and install an audio sequencer.Īlternative replacement software: Rosegardenįunction names: Digital Audio Workstation/Audio sequencer The configuration depends on the capabilities of the soundcard, but be sure to check the "Realtime" box and select the proper input and output devices.Ĭommon configurations include "Force 16bit" and 44100 sample rate.įor more information, be sure to check out. This application will then be found through Applications -> Sound & Video -> Audio Production -> Jack Control. To be able to configure and start the JACK daemon through a graphical interface, start up a terminal and install QJackCtl with this command: sudo apt-get install qjackctl When starting JACK through QJackCtl, be sure no other process is using the soundcard. If only one soundcard is present, JACK will take control over it and it won't be possible to play any "regular" audio while JACK is running. Note: The easiest setup is to have a secondary soundcard with which JACK will be used. To accomplish this and to optimize the sound processing to lower latency, the JACK system is used. When it comes to the audio hardware in Linux, the kernel and ALSA (Advanced Linux Sound Interface) take care of getting it to work.īut this stack is unable to provide a transport channel for different audio applications to "talk" to eachother (audio sequencer and drum machine, for example). But later on, when applications should be connected, it is needed - so we might as well get used to it right away. Note: You don't need to start JACK through Qjackctl in this step, it can be handled from within Ardour. This kernel is the same as the standard kernel but with real-time support, so everything should be as normal and the kernel can be used even when the machine is not used for music production. Now, reboot the system and boot into your -rt kernel (should be default). Please note that creating or modifying /etc/security/nf may cause conflicts with the JACK written /etc/security/limits.d/nf settings.Įmail from Linux Audio Users mailing list: JACK will write the following during post-installation to /etc/security/limits.d/nf: Note: Modifying /etc/security/nf Should Not Be Required Anymoreīeginning with the Ubuntu package jack-audio-connection-kit-0.118+svn3796-1ubuntu2 editing of /etc/security/nf should not be required. Sudo su -c 'echo - nice -10 > /etc/security/nf' Sudo su -c 'echo - memlock 250000 > /etc/security/nf' In the terminal, issue these commands: sudo su -c 'echo - rtprio 99 > /etc/security/nf' To install this kernel, open up a terminal and run: sudo apt-get install linux-rtĪlso, we need to give the audio-group the rights to set real-time priorities, lock a big amount of memory and prioritize processes in general. This makes sure that the audio recorded gets the highest priority possible so the audio quality will be good without skips. (Note that if you are using UbuntuStudio, you do not need to perform this step, as the real-time kernel is already in use). The first vital step to a working environment is to have a real-time kernel. This page will detail where to check if your hardware is compatible, depending on your audio setup. ![]() Before considering buying new hardware, please check to be sure your hardware is ok with ALSA and JACK. ![]() Things are a bit different in the linux world. Please add comments where the two differs.īefore everything (and especially if you plan to use Firewire hardware), you have to be sure your hardware is supported by Ubuntu Studio.įor Mac and Windows platforms, manufacturers usually provide ASIO-compliant drivers. Note: This guide is based on Ubuntu 8.04, not Ubuntu Studio. Hopefully this will be useful for people that have no or little experience in the area, or producers switching from a Mac/Windows environment. This page will try to describe the process of getting started with music production in Linux in a user-friendly way. ![]()
