Hi, sorry my previous message was incomplete ... continues below:

3) applyplugin applies plugin to audio file.
you can do the same as sox effect as
sox input.wav output.wav  ladspa  /usr/lib/ladspa/delay.so delay_5s 1 .5
(applies abovementioned default delay,dry/wet parameters and plugin to
input.wav and writes result into output.wav)
regards, Mikko
