Remove text from a filename

Hello there,

I could use some help removing text from a filename. Basically I want to remove all text after a specific word (including the word). For example:

Filename: 07 Blue Yodel No. 9 (Standin' On The Corner) (mono) - Jimmie Rodgers3.wav

In this instance I want to remove everything after (AND INCLUDING) "(mono)"

Thanks in advance for the assistance,

Use a "Format value" action on _FILENAME field, with this Format string:
$trim($left(%_filename%,$sub($strstr(%_filename%,'(mono)'),1)))

Or use Convert>Filename-Filename
Source pattern: %1 (mono%2
Target pattern: %1

Thanks, ryerman. Much appreciated...worked like a charm.

Thanks, ohrenkino. Also worked like a charm! Cheers. Be safe out there.
