I wasn't sure which forum to post this in but here is my question. I'm taking some tapes and converting them into .wav files on my computer. The tapes have quite a bit of hiss on them. The program I am using allows me to basically cut off any sounds beyond a certain frequency. I randomly chose 10khz which seems to get rid of the hiss. Am I cutting off any of the "music" at this level? Should I set the cutoff point higher? Or can I go even lower? Thanks for any help.
