Audio preview while tweaking audio filter not reliable?

[Malcolm Wright]

Hey all,

Has anyone noticed that the sound changes when you open and close the dialog of an audio filter such as low pass filter?
Try it: put a clip on the timeline, apply a low pass filter and change the settings so the sound is markedly altered. Then, as the clip is playing, open and close the filter settings dialogue (by double clicking on the filter in the information window).

I'm finding this very confusing because if the sound changes depending on whether the settings dialogue is open or not, it becomes impossible to tweak the settings and be sure that is how your clip will sound at render time!

Can anyone shine some light on this?

Thanks,
M.

Weird: it does not do it for me now. It still does it in the project I was working on when I first posted, but when I try in a fresh project, it works fine...
