How To Remove Parentheses and its contents?

Support
#1

Hello,

I have a mp3 with the title:

Welcome To The World Ft. Kanye West And Kid Cudi (Produced By Kanye West)

and I want to remove the parentheses and its contents so it just says:

Welcome To The World Ft. Kanye West And Kid Cudi

Any help would be great! Thanks in advance.

This should you get started

This expression removes all parentheses with its content:

$regexp(%title%,'\s*\(.+?\)',)

and this removes only the last one:

$regexp(%title%,'\s*\([^)]+\)([^(]*)$',)

I have found these expressions in here but i don't know where.
