Introduction to aRts
The Analog Realtime Synthesizer (aRts) enables the playing of multiple audio or video streams concurrently - be it on the desktop or over a network. ARts is a full-featured sound system and includes filters, a modular analog synthesizer, and a mixer. Its architecture allows developers to create additional filter plugins and users to apply sequences of filters using a graphical drag-n-drop approach. Video support is available for MPEG versions 1, 2 and 4 (experimental), as well as the AVI and DivX formats.
ARts is a core component of the KDE 3 desktop environment and provides the basis for the KdeMultimedia package. However, it can also be used independently of KDE (i.e. doesn't use Qt or KdeLibs for most things).

On x86_64, aRTS 'configure' fails to detect if the hardware provides SSE floating point to int conversion instructions.
Apply the following patch to allow aRTS to use SSE instructions and hardware float to int conversions on your x86_64 machine:
