Adjust treble and bass on sound playing


I’m searching to adjust the treble and bass of sound from a video or mp3 to make an effect of door open/close. Somebody has a solution ?

Thank you !


I would simply use an audio editing software, like audacity. Edit your mp3 file, save it and then play it with OF.

It’s a solution but it can’t be possible to control the effect in an interactive way.

You can render outside a processed file, and then to cross fade mix both files (clean vs processed) in real-time. Very easy with basic sound playing in OF.
If you need “more accurate” real-time you can search for some addon to process eq in ofxaddons

Thanks, this tricks works !
