I do not reproduce the problem on macOS using version 19.04. I will try Windows next, but I believe it will work. and more information is needed. For example, what are the Properties of your audio clip? And what is your version and number of bits?

I recorded it with OBS in case that helps

I also experienced problems with Reverb.
The moment I activate the filter, the problem appears.
I tried three ways:
-Add filter to the source (WAV audio from the playlist)
-Add WAV source to timeline (automatic creation of video track) and add the filter
-Add WAV source to timeline to an audio track created earlier.

In all three cases, when the Reverb filter is activated, the error occurs.

I reproduced this and fixed it for the next release. The problem occured when local/region setting us using comma for decimal point. This is an easy fix for your current install. You can copy the attached ui.qml.txt file to share\shotcut\qml\filters\audio_reverb\ui.qml in your installation. Do not forget to rename it from .txt to .qml replacing the old one.

P.S. There were other audio filters affected by the same bug:

• Compressor
• Expander
• Notch
