[CM] Snd/CLM question: :decay-time for with-sound

[Jacob Rundall]

I was looking at what I think is the current documentation for with- 
sound (https://ccrma.stanford.edu/software/snd/snd/sndscm.html#wsdoc)  
and I see that there doesn't appear to be a decay-time parameter  
anymore.  I want to make sure when using a reverb like nrev that with- 
sound can add some time at the end of the computed audio file so that  
the reverb can decay naturally.  If I remember correctly, the decay- 
time parameter used to accomplish this.  I can throw a silent  
instrument call in at the end of my computed file to accomplish this,  
but is there a more elegant way?

Thanks,

Jake Rundall
