Technical Q&AQTW 19 - QuickTime for Windows API & Overlaying Sound Effects (1-May-95)Q My application allows users to overlay sound effects on a long sound track while the track is played back. To accomplish this, I use two sound tracks in a movie -- one with the long sound track and the other with the short sound effects. I use InsertTrackSegment, DeleteTrackSegment, and InsertEmptyTrackSegment calls to implement these functions in my application. Are these calls supported on QuickTime 2.0 for Windows, and can I successfully play back a movie with two sound tracks using QuickTime 2.0 for Windows? AAlthough QuickTime for Windows version 2.0.1 supports multiple sound tracks, it allows only one track to be active at a time, because Windows 3.1 does not support mixing of sound tracks. The InsertTrackSegment, DeleteTrackSegment, and InsertEmptyTrackSegment calls are not included in the QuickTime for Windows 2.0.1 API. Technical Q&A Previous Question | Contents | Next Question |
