Thanks for the reply.
I do not think there is subtle low fequency information, or any other audio whatsoever there.
I gated the hihat to get rid of crosstalk and exported it and imported it to another track.
Changing the treshold does not help.
It shows now other transient markers than the markers in the picture.
The hihat is the most constant factor in this song, so I wanted to use audiosnap on the hihat to set the project tempo right for this song.
