Hello all!
  First of all thanks for the help and the response last time I wrote. this time I've just a question or a proposal.
  It was just something I missed. Sometimes I would really like to have a distortion- or overdrive-effect. Especially for working with guitars or sometimes also for working with drums this is a nice effect. 
Another nice and wellcome thing would be a kind of EQ.
  As for the EQ I have an idea, but I'm not really sure if I got the idea of the EQ right. I thought of a combination of bandpass-effects- and amplifier-effects. Then it's the programmer's choice either to take the normal bandpass- or the resonator-filter.
  I think it would be something like this without having a special effect for this:
ecasound -a:1,2,3 -i myfile.wav -a:1 -o 80-250.wav -eb:165,85 -ea:120 -a:2 -o 250-800.wav -eb:475,225 -ea:80 -a:3 -o 800-20000.wav -eb:10400,9600 -ea:200
  Is this idea of an EQ correct?
My kindest regards
            Julien
