Hello all, I'm new here. I have to synchronize 15 wave files played by 15 different processes in the same pc (linux server). I assume the files are recorded (I record them ) with the same rate so I should not have any kind of audio synchronization problem. These files are quiet long (4 hours) so, if I let the processes just play them without synchronization, I'm sure after some time they are not aligned. Does someone know how to solve this problem with QT's inter-process communication ? Thanks P...
