Setups for Ubuntu Studio

Ubuntu Studio is a Debian-Ubuntu distribution designed for media development.  It comes with a powerful suite of audio, video and graphics tools that makes for a great workstation.  Mostly, everything just works.  It uses the Xfce desktop that is lightweight but a bit spartan compared with Ubuntu’s gorgeous Unity desktop.  I like Xfce more, and it is better for a workstation.  Ubuntu Studio is all fully open source software. This RadioTed.com shows you how to add what is needed to make a great radio station with mostly free software.

We will also cover DreamStudio, which is a gorgeous full featured  Standard Ubuntu based media workstation, featuring Audio, Video, 3d graphics, animation, etc.  DreamStudio does not worry about all the applications being open source, just that they are affordable, and VERY nice.

Jack Audio Connection Kit

The Jack Audio Connection kit connects up all your audio applications and interfaces within the computer.  It comes working out of the box in Ubuntu.  For serious work, a bit more setup is a good idea.  There is lots of advise on the internet that is outdated for Jack. NetJack connects computer’s audio together in a network.  Not for the casual doodler, but very powerful.  RadioTed.com will make it all come together.

Part of what makes Jack2 easy to use is the KXstudio utilities that tie Jack2 together with a friendly, understandable  user interface, with additional powerful tools to build a great audio workstation.

Rivendell

Rivendell is a powerful and competent open source complete radio automation system.  You can get it free as a completely set up Centos based “appliance” that will run an entire radio station on a garden variety desktop from Paravel Systems.  (They will also sell you computers all set up to run, and provide technical support)  You can use it as the basis of an entire radio production center with server, multiple workstations, integration with audio workstations, etc. You could extend the appliance, but miss out on all the other features that Ubuntu Studio brings to the party.  You will get guides here for using Rivendell whether you use the Paravel appliance or adding it to Ubuntu Studio. The Rivendell appliance is designed to set up once, get it right and then never update or change (except to cure bugs) until you are ready to do a major upgrade.  It is an appliance!

Rivendell plays just the same whether on the appliance, Ubuntu Studio or DreamStudio.  The other applications and tools are different. A Ubuntu Studio installation will have regular audio DAW software to help out, and good tools for managing the Jack2 and other interfaces.

Use PulseAudio with Jack Audio Connection Kit?

Ubuntu Studio 14.04 uses Pulseaudio -> Alsa -> Jack as the connection interface for audio devices.  Pulseaudio is a very simple interface, and with it most audio cards just “show up” and play with Jack as the pulseaudio-sink and pulseaudio-source devices on the Jack patchbay. In the olden days (Ubuntu Studio 10.04 and before) Pulseaudio

Don’t Edit /etc/security/limits.conf

Tags : 

There are a number of sites that say to edit /etc/security/limits.conf. Ubuntu Studio 14.04.2 automatically makes the entries for Jack in /etc/security/limits.d/audio.conf on installation. The debian.tryphon.eu  Rivendell package automatically sets them up in /etc/security/limits.d/rivendell.conf These files get read in by an include statement in /etc/security/limits.conf so all is good, don’t edit limits.conf.
