Ok, thanks for explanation !
Does asking  "a program using snd_pcm_copy  family function" would be 
correct ?

(or using snd_pcm_meter functions, as Abramo Bagnara  said later on the 
thread)


In fact, the relation between plugins you define in .asoundrc and their 
relative c function
is not clear to me , so I'm now going to figure out out how it works, 
but if you have lights
on the subject,  it would be ok.

As you can see, i'm an unexperienced developper so be patient  ...
