Phase shift in the dialogues

I notice a phase shift in the dialogues of the feature film that I am mixing. the phase shift is random. sometimes on the 1st sequence it is present, the next reading, it is absent. auto align post 2 was used and the pole and tie files are aligned we see the modification made by the plugin in ara2. It is true that the computer manages 1038 tracks but it does not seem to have any problem with that. Initially I put it down to ARA2 but it’s impossible because sometimes there is no phase shift then the next reading it reappears again. I looked at the automations and routings hoping to have made some mistake, that’s not the case. do you have this type of problem?

Je constate un déphasage dans les dialogues du long métrage que je mixe. le déphasage est aléatoire. parfois sur la 1ère séquence il est présent, à la lecture suivante, il est absent. l’alignement automatique post 2 a été utilisé et les fichiers poteaux et attaches sont alignés on voit la modification apportée par le plugin dans ara2. Il est vrai que l’ordinateur gère 1038 pistes mais cela ne semble pas poser de problème. Au départ je l’ai mis sur le compte d’ARA2 mais c’est impossible car parfois il n’y a pas de déphasage puis à la lecture suivante il réapparaît. J’ai regardé les automatismes et les routages en espérant avoir commis une erreur, ce n’est pas le cas. as-tu ce type de problème ?

You need to render “to new file” to make it permanent.
It’s an ARA2 problem, the team is trying to fix this at this very moment.
Unfortunately, you will lose the metadata, so make a safety copy of your DIA tracks.

hello fredo.
Thank you for your response, unfortunately I applied the “make permanent” procedure. what is amazing is that sometimes during a reading there is no phase shift afterwards. the phase shift returns, then it leaves again… it’s incomprehensible.

If you do “make permanent”, it’s not an ARF problem. But I have my doubts. I think you may have missed some clips, which would then have remained under ARA.

Nuendo doesn’t have a utility to identify all the clips in a session affected by an extension. This is a problem I’ve discussed elsewhere. It would be so useful! For a hundred reasons.

Bonjour. Merci pour votre reponse. Helas ca ne peut pas etre un oubli puisque sur deux ou 3 lectures consecutives du meme passage dephase ou non et sur des pistes aleatoirement differentes. Je pense plutot à un plugin qui viendrait contrarier la compensation de delai creant ainsi un déphasage… plus specifiquement à acon deverberate. il.suffit que le plugin ne rende pas la meme valeur pour une raison x ou y et on crée le probleme…je vais regler le probleme en utilsant le traitement hors ligne des pistes cincernées par des plugin specifiques qui n’ont plus a etre modifiés. Je vais faire les tests.

Good morning. Thank you for your reply. Unfortunately it cannot be an oversight since on two or 3 consecutive readings of the same passage out of phase or not and on randomly different tracks. I’m thinking more of a plugin that would counteract the delay compensation, thus creating a phase shift… more specifically acon deverberate. it is enough that the plugin does not return the same value for a reason modified. I’m going to do the tests.

You probably shouldn’t run deverberate live as it is a NN based plug-in and those are never exactly the same. This shouldn’t really affect time DPC (phase) however the change in process might make it feel like it.

Try offline rendering the deverberate clips instead and see if it goes away. If it does it’s caused by deverberate and if needed I can ask Stian if that is to be expected.

j’ai fait les tests que je voulais et en effet le plugin acon deverberate crée un phenomene de dephasage aléatoire. le traitement hors ligne puis la copie du meme fichier sur une piste sans le plugin acon regle le probleme pour l’instant. merci erik pour.la confirmation de.ce que je présentais. qu’est qu’un plugin NN?

I did the tests I wanted and in fact the acon deverberate plugin creates a random phase shift phenomenon. offline processing then copying the same file to a track without the acon plugin solves the problem for the moment. thank you Erik for.the confirmation of.what I presented. what is an NN plugin?

This is super simplified as I do not fully understand it all.
NN means Neural Network. It’s a sort of AI trained plug-in and in general AI and NN based plugins do not work the same way as most other plugins. They analyse and take”decisions” based on the analysis, and the outcome of the “decision “ is not always exactly the same. So the result when processing the same audio file is not always identical. It can’t be apparently (for reasons that I do not understand).

Ok ! Thank’s
