Tape hiss and the clipboard
Posted: Sun Oct 17, 2010 11:24 pm
I am converting a pile of cassette tapes to MP3 files. The tapes have a fair amount of hiss on them, as well as some motor-boat fluttering noise. I have been able to reduce most of the noise by copying a portion of the leader tape to the clipboard and then applying noise reduction to the rest of the tape using that sample.
My question is this: I have 10-15 seconds of fairly constant noise at the beginning of each tape. What is a reasonable amount of noise to copy to the clipboard? Is there an advantage to copying a large amount -- several seconds -- so the noise reduction algorithm has a lot of material to work with? Or should I copy only a fraction of a second -- just enough to let it know what noise I need to eliminate?
Is there a standard? Or does it really make any difference? Any thoughts?
