How do i install ladspa plugins?

[hinsn]

Hi all,

I´ve been trying really hard to understand how this works, but somehow I can´t figure it out...

I want to apply filter effects to isolate frequencies that I see in a spectrogram to train my hearing. I searched for filters in "Find Transforms" but there was nothing. In this forum, someone suggested to use LADSPA plugins.

Can anyone help me out here?
