when i have a really old record and there's too much hiss, i capture a noise reduction profile from the initial 3-5 seconds and then subtract that from the overall wav form.. this removes the hiss (though sometimes i keep it if i want that original vinyl sound). the problem is, the records low and midrange game goes away and it's alot more treble-ey.. anyone have another method of getting that hiss out without having the treble effect?

now i'm starting to question if i'm using the right method. this trick that i'm using is actually for recording vocals with a certain level of echo.. i don't think it's meant for records.

are the standard "hiss reduction" filters the way to go?
