| === Real Time Kernel === Ubuntu Studio uses the real-time kernel which is modified with the preempt patch by Ingo Molnar. This helps reduce the amount of [[http://en.wikipedia.org/wiki/Latency_%28audio%29|latency]] which is very beneficial for audio work. |
'''Real Time Kernel''' - Ubuntu Studio uses the Ingo Molnar PREEMPT patched real-time kernel (for more information about the real-time kernel see the [[http://rt.wiki.kernel.org/index.php/Frequently_Asked_Questions|RTWiki FAQ]]). This helps reduce the amount of [[http://en.wikipedia.org/wiki/Latency_%28audio%29|latency]] which is extremely beneficial for audio work. |

| === limits.conf === | '''System Configuration''' - The Ubuntu Studio team has already configured the Ubuntu Studio system to help maximize the real-time kernel. The user is included in the ''audio group'' and the ''limits.conf'' file is specifically configured. '''JACK Sound System''' - Along with the ubiquitous [[https://wiki.ubuntu.com/PulseAudio|Pulse Audio sound server]], the powerful JACK sound server is also included. And luckily it's all automagickally configured to work well togther already. |
Ubuntu Studio is an officially recognized derivative of Ubuntu specializing in multi-media creation.
Ubuntu Studio provides a suite of the best open-source applications aimed at the GNU/Linux audio, video and graphic enthusiast as well as the professional.
Completely free to use, modify and redistribute. Your only limitation is your imagination.
Next, let's contrast how Ubuntu Studio differs from Ubuntu.
Ubuntu Studio vs. Ubuntu
Some differences are more evident between Ubuntu Studio and plain, vanilla Ubuntu. These would include a different theme and background and a different battery of installed applications.
But Ubuntu Studio is more than just Ubuntu with a slick theme and extra packages installed. There are several subtle and prevasive differences including:
Real Time Kernel - Ubuntu Studio uses the Ingo Molnar PREEMPT patched real-time kernel (for more information about the real-time kernel see the RTWiki FAQ). This helps reduce the amount of latency which is extremely beneficial for audio work.
The low levels of latency that can be achieve in Linux with the real-time kernel can also surpass those available under Windows and Mac.
System Configuration - The Ubuntu Studio team has already configured the Ubuntu Studio system to help maximize the real-time kernel. The user is included in the audio group and the limits.conf file is specifically configured.
JACK Sound System - Along with the ubiquitous Pulse Audio sound server, the powerful JACK sound server is also included. And luckily it's all automagickally configured to work well togther already.
