Re: [ARSCLIST] cassette crackle

[Tom Fine <tflists@xxxxxxxxxxxxxxxxxxx>]

Were these tapes all recorded by the same person on the same system? If so, it's probably something 
intermitent (sp?) in the original recording chain -- a dirty connector or the like. If they are 
off-air recordings from the radio, any number of atmospheric and in-house electrical things can 
cause crackles. If they are, for instance, Grateful Dead concert recordings made off a common buss 
from the mixing console or even from a shared mic array, anything from connector-itis to electrical 
spikes to things happening on-stage can cause crackles. And of course, if they are from LPs or other 
grooved disks, that could just be surface problems.
