[Solved] De-synchronized Movie player and AUaudioFilePlayer



  • As found in a previous post:

    The culprit is 48KHz files.

    44,1KHz files behave ok.

    Hello,

    For an interactive installation I'm playing with the speed of a video & sound of a women singing.

    Since I have to correct the pitch of the voice when it go slower, I separate the sound (AuAudioFilePlayer) and the video to be able to use pitch corrector tool  (AUNewTimePitch & AuVArispeed).

    And its desinchronized, sound is alway ahead (around 7-8%). 

    Even when I link the position of the AuAudioFilePlayer to the position of the Movie Player and play it at normal speed, it desinchronized...

    I don't understand why and how to correct...

    Any idéa?

    I see that FPS is locked on 30FPS on Isadora 3.02 (event when I put it at 25fps everywhere - preference etc) it might be part of the problem...

    Thanks!

    This article shines light on that behaviour: https://community.troikatronix...
