Hello - in 5.3.3 (OS 13.6.3), when we edit and save an audio file, the QLab waveform view doesn't refresh. Audio playback does reflect the changes, but the displayed waveform is true to the earlier version of the file; a new cue also exhibits the old waveform. This persists up until QLab is quit and restarted (even closing/reopening the workspace doesn't bring a refresh). This can get confusing when the waveform shows silence but sound comes out! Was the issue you saw Jean?
Vaguely related, in the same version, replacing an audio file target with a longer audio file still retains the previous shorter duration, so the longer file will be cut off. There was discussion here in November, was there any outcome?
thanks, and best
M
