I just used the de-hisser that comes with Magix's Studio 11, and I've got to
say, it worked really well. I used it to remove hiss from a recording I
made using an old AT 9400 stereo mic. The mic sounds great, but it
requires massive amounts of gain--and this added tons of hiss. The
Magix de-hisser removed it completely. I had recorded a nylon-stringed
guitar; to say that I am impressed with the de-hisser's work would be
a massive understatement. Of course, the software costs $79.00 US,
but I've been using Magix's software for a while, and it is worth every penny.
I'm sure it would remove your tape hiss, and for the price you get a complete DAW. Does anyone else use this software?
I love it, and have had nothing but great results with it. There seems to be
a conspiracy of . . . silence? prejudice? about this software. I never see it
mentioned, except to dismiss it with a word or two. Strange . . . .
