Wrong Tempo in export file

[Orchid1st]

Hello,
I saw a lot of issue concerning the tempo in the export file, but I didn't find a solution for my problem in the recent posts.
I have a simple project on Tracktion 12 composed of 4 bus. Each bus is composed of 2 wav tracks (right and left).
There is no change of tempo but just a change of signature one time.
When I export the project in one file (wav, or mp3), the tempo (and also the pitch) is lower in the export file than in the edit panel.
Please do you have any idea about the cause of that problem?

Thanks a lot for you help

Hello

Hey! Never had a problem with tempo in WF. Check if there is a check mark in the Render box next to "Render at 1 x Play-Speed"? If it is, then remove it and the rendering will be fine. In all other cases, you would hear the wrong tempo when editing the Project.

You may also be mixing 48 and 44.1, which results in a lower tempo render.

Hi,
No the "Render at 1 x Play-Speed" is not ticked, but I tried to ticked it to test the effect on the export file

The sampling frequency during the recording = the sample rate during the exportation = 44100Hz

If you render each bus separately inside the project (just hit render to a new track) do you still hear the same problem on all the renders? If not just render first to create stems and then export the track using the stems instead of the live buses.

In that case, the problem still remains for each "sub-export".

Hooo

I just found something very strange. In fact, if I read the export file from the explorer file of Waveform all is OK, but if I read the export file with VLC, Groove Music or Window Media Player the problem appears.
