Parametric EQ options?

Are there any options for a parametric EQ on Picoreplayer?

Even if command-line?

Or does anyone know a path to a Parametric EQ running on a RPi that is also running Squeezelite?

It would help with some system issues I have. The graphical EQ is nice but a parametric EQ would be more helpful for my purpose.

I posted this in another forum, I'll go try to hunt it down and kill it. Sorry, I didn't intend to cross-post this.
