Re: [Sndobj-devel] Connecting double Interp

[Victor L. <Vic...@nu...>]

what is happening is that your 2nd envelope is not having
much effect. The comb filter will repeat the first short beep
every 1/2 sec, decreasing its volume by half each repeat. The
envelope is going from 0 to 1 in 3 sec, increasing as the
beeps decrease. If you want amplification then it has to
go above 1, but the sound will decay because the comb
filter makes it decay. I am not sure what you want, but
do you understand what is happening?
