Terry,
What is your roaster? Is it an iRoast2? I will be interested in  
hearing if the stethoscope works. I suspect it will simply amplify  
everything and one may still not be able to distinguish the cracks or  
snaps from the blower noise. Do let us know.
We are leaving for China this Saturday for three weeks. I hope I will  
be able to locate your report when I return.

you mention:>>>electronic device keyed to a specific frequency so as to recognize 'pop' from 'snap'<<<
snap,  crackle and pop in roasting is kinda the same thing as scp in rice crispies. you hear it or you do not hear it. if it heats up, snaps and cracks it's roasting coffee, add milk and we have rice crispies.

It was in one of the discussions a few months back. And since I don't
remember many specifics about last week, I couldn't begin to remember who
started the discussion or what exactly they were working on (the device that
is). The info as I do recall filtered the frequency to that range where in
the bean popped and up to the range of the snap. I think the intent was to
record when these freqencies or decibles were acheived, not so much in
reproducing the sound range. Does that make any sense? *I know where in I
speak, but I may not be able to articulate the thought to you.* A response I
have fostered to my wifes statement of "I don't know what you are talking
about." (which is most of the time).....

I assume a stethoscope for cracks could be easily located in the Plumbing
Tools section - sounds like a perfect fit...

p.s. maybe too late - spew alert!

O.K. Dave....Jeez...that reminds me of the response from the old Chipmunks
song....
Anyway...got the stethoscope at the Auto parts house, $10.00...not bad...but
as yet I haven't gotten to hear the cracks. Actually I think it's worse
because with the scope plugged into my ears, I can't even hear the usual
faint sound of the crack. But I have narrowed down which lifter has been
making that tic-tic tic sound when I start up my truck.
back to the think tank...

Terry - run a batch thru a hot air popper so you'll know the sounds of
popping.  That should help you whn you go looking for these same
sounds in the noise of a different setup...

I had been using a Rosto and it being a little quieter than the IR2 I have
heard the sounds of 1st crack and faintly could hear 2nd (starting into my
range of hearing loss, high frequency).
As for the acrobats of the popping beans, when you use an oven then you get
the whole act. Hear the pop, watch the beans spin and hop.
Thanks for the 2 cents brett, I'll see if I can't make it increase through
investments in my techniques.
