A more negative value entered for nice reserves more CPU time for real-time audio processes. In 9.10, the 'Ubuntu Studio Controls' provided under System>Administration permit the user to 'Enable Nice', allowing the use of wireless networking and proprietary graphics cards drivers while maintaining low audio latency free of XRUNs (audio drop-outs) in JACK. The scheduler allows applications to request immediate CPU time, which can drastically reduce audio latency. Since much of the real-time patch has now been implemented into the vanilla kernel, and considering the difficulties in maintaining linux-rt, Ubuntu Studio decided on using linux-lowlatency in its place. Low-latency kernel Īs of Ubuntu Studio 12.04, the default kernel is linux-lowlatency, which in essence is a generic Ubuntu Linux kernel, with a tweaked configuration to allow for stable operation for audio applications at lower latencies. As of version 10.10 of the Ubuntu Studio, the real-time kernel is no longer available in the repositories. 10.04 Ubuntu Studio, in contrast, does not include the real-time kernel by default. It has been reimplemented in the 9.04 Ubuntu Studio release and stabilized with the release of 9.10. The 8.10 Ubuntu Studio release lacks this real-time kernel. The real-time kernel, first included with Ubuntu Studio 8.04, was modified for intensive audio, video or graphics work. The original version, based on Ubuntu 7.04, was released on. Ubuntu Studio is a recognized flavor of the Ubuntu Linux distribution, which is geared to general multimedia production.
