thanks for your quick reply.
i've already tried to use Audio::LADSPA, but for some reason it does not work on my machine...
maybe i was a bit too vague in my original question.
what i want is that everytime a new sample is generated, ie every time 
        my $v2 = sin($counter/2*3.14) * 128 + 128;

        $data2 .= pack("c", $v2);

generates new data, this data should be played by the soundcard.
this way, by including additional manipulations on $v2 using variables send to the subroutine by moving a scale-widget, the sound should change.
i also would like to program the filters, fx, etc myself (that is, if i am able to do so...)
