Hello, I believe that sox does not support finding/listing plugins. Fortunately, the packet "ladspa-sdk" in ubuntu repos ship with tools: 1) listplugins which lists the plugins you have available. For example it lists one of my plugins as /usr/lib/ladspa/delay.so: ... 2) analyseplugin lists the plugin details e.g. analyseplugin /usr/lib/ladspa/delay.so then lists the (input) ports of that plugin: ... "Ports: "Delay (Seconds)" input, control, 0 to 5, default 1 "Dry/Wet Balance" input, control, 0 to 1, default 0.5" ... 3) applypluginsox input.wav output.wav ladspa /usr/lib/ladspa/delay.so delay_5s 1 .5 applies abovementioned default delay,dry/wet parameters to the plugin. regards, Mikko On Tue, Jun 16, 2020 at 7:16 PM Andrey Trofimov wrote: > Hello! > > I am using ubuntu on windows and I managed to install some ladspa plugins > (i think), but I can’t figure out how to use them.
