Everyone knows that XPression is the fastest Real-time motion graphics engine in the industry today, but did you know it handles audio files, also? The best format for audio files is a WAV file sampled at 48KHz (16-bit). The WAV files can be added to a Scene Director to trigger at a specific time, and it is even possible to add keyframing to adjust audio levels. Monitoring the WAV files on the timeline is also possible. To find out more, watch (and listen) this video.
