You certainly don't need to tune and tweak Windows XP for audio applications, but you can achieve better overall performance if you do.XP requires less tuning for audio applications than previous Windows operating systems. In fact, XP delivers excellent audio performance without changing anything.
However, with all Windows OS's, there are many features and functions that are quite simply not required. Excessive graphic activity, system maintenance functions, background tasks and automated hardware management tools, all contribute to the large number of unnecessary features that can be trimmed down to suit an audio PC (DAW - Digital Audio Workstation).
In addition to trimming down unnecessary XP features, it is also possible to adjust the priority and cycle length of CPU usage to suit the requirements of an audio computer.
