Something is weird with the compressor? #23

Are you sure this is working right?

sf_advancecomp(&STX[i], 48000, 0, -40, 0, 10, 0.25f, 0.15f,
                    0.006f, // predelay
                    0.090f, // releasezone1
                    0.160f, // releasezone2
                    0.420f, // releasezone3
                    0.980f, // releasezone4
                    0.000f, // postgain
                    1.000f  // wet
                );

Now this is fed with a 512-sample array

And the result is (at sample 287)

Is there some extra gain added?
