Audio filter.

[BagPuss]

Can anyone inform me how I add an audio filter to the entire video all in one go. I can do it one at a time to each individual segment but of course this takes ages. I am using 2019 ultimate.
Thank you.

Not possible, highlighting a range makes Audio Filter inactive, don't know of any other way

You could try using Copy and Paste attributes

First I would make a copy of your project

Add audio filter to the first clip, right click for Copy Attributes
Shift + Click ( first and last clip) to select multiple clips, right click for Paste Attributes

export your full audio tracks as wav file
mute all tracks
Load the wav to new track
apply filter

asik's suggestion would work, though it would need to be virtually the last step in the project, and only done once you are satisfied with all the video editing parts of it. Otherwise, if you later wanted to edit part of the video, it would throw parts of the audio out of sync...
