Cross-platform Audio Creation Tool
Appearance
XACT is an audio programming library released by Microsoft as part of the DirectX SDK. It was originally developed for Xbox development, and was later modified to work for Microsoft Windows development as well.
The XACT Audio Authoring Tool is a companion application used to organize audio assets into wave banks (single files containing multiple WAV files) and sound banks (single files containing instructions for playing the WAV files in wave banks). The wave banks and sound banks for a project are subsequently called by XACT from within the program.
Support for XACT has been carried over from DirectX to XNA. The XACT Audio Authoring Tool is also available in XNA Game Studio Express Beta 2 onwards.
