Didn’t Hear First Crack?

I attempted my first roast on my Kaldi home roaster. I did not hear audible cracking until the 425F (13 mins) mark and my coffee was darker than anticipated after dropping a minute after what I thought was first crack. Being that the temp was so high when I hit audible cracking and the beans were roasted much darker, I assume I blew by first crack without hearing any audible cracking. Does anyone have any ideas what may cause this to happen?!

Thanks in advance!

Its all experience ... some beans will be very loud/ some quite. The density of the bean seems to have a big impact on this. Higher elevation grown coffees tend to be more dense. I do find 1st crack to be more of a pop sound and 2nd crack to be more of a crack sound (like snapping fingers). On my roaster I hit 1st crack around 385 / 2nd crack around 430. Your temp readings are a bit different than my roaster, I would start listening for 1st crack around 380 on your roaster. Good luck.
