Audio playback is always streamed while authoring in Wwise. If you have specified streaming and defined Music Track look-ahead time in the Music Track Property Editor, these values will be used during streaming. If you have not selected the streaming option, the default Music Track look-ahead time of 200 milliseconds will be used. To increase flexibility and to avoid sync and voice starvation problems during playback, you can adjust the Music Track look-ahead time as a user preference.
To set the Music Track look-ahead time:
From the menu bar, click Audio > Audio Preferences.
The User Preferences dialog box opens.
In the Sound Engine group box, type the amount of look-ahead time in milliseconds in the Music Track look-ahead time (ms) text box.
Click OK to save your settings.
From now on, the sound engine will use this amount of look-ahead time to seek streamed data when playing music in Wwise for Music Tracks that do not have defined streaming settings.
