Audio Pitch: Timeline vs. BPM

[pfelberg]

Hi. I am very used to play videos with audio tracks in Resolume.
I´ve learned that selecting playmode to TIMELINE was allways better, considering the audio track within a video clip. It allways worked ok to me that way.
I don´t know what, when or how that have changed in Resolume, but I got no previous warning.
During a presentation last week, I had just one single clip with audio and I had a very specific moment to play it.
It was a live nightmare!!!
The audio was being played in a very low pitch and after a few seconds I was obliged to stop the entire presentation.
It took me a few seconds to realize to set it back to play in 120 BPM mode. When I did that it played correctly, but the damage was already done.
No, there was no change in the way I render my clips whatsoever.

This weekend, another presentation and 14 video/audio clips to be played - every single one in a very specific moment.
I was not expecting to get the same thing. I was wondering something was wrong with the "glitch file" or a bug somehow happened in Arena. Course I dedided to test each file before going live in Arena. Guess what? I got the same thing for every file. No way to play it in TIMELINE mode.

Any clues or comments are welcome.

Thanks

Paulo

My first guess would be that the Composition speed is set to a low value, but that would reset if you create a new composition.
its the slider on the right of the M http://resolume.com/manual/en/r5/compos ... n_controls

Course that was the first thing checked. Composition speed was ok and so was the clip speed. I couldn´t find any parameter on the gui that could explain such behaviour.

Could you post a screenshot of your audio preferences, please?

do you use any other audio app while using resolume?
If the other audio app changes the sample rate after resolume startup that could cause a slowdown, for example if you use resolume at 96kHz and the other audio app changes SR to 48kHz you'd hear the audio slow down to half speed.

No other audio app running. Just Arena.

That's a really high buffer size. Could you try decreasing it to 2048 or 1024?

I just started the system to try changing this value but guess what.... What??? All videos were just playing nicely on timeline mode. No adjustments. Pure magic.
So I will have to wait for another issue to happen to test changing buffer values.
