Thanks, I am trying to find a way to focus on a whisper that my voice dictator picked up, it is very silent, there is a lot of hiss and I was wondering how to single this whisper out to hear it

I have some experience with this. (I like Adobe Audition, but it's rather pricey) I've actually found that a lot of noise-removal software just doesn't do the trick because it often fails to isolate the sound I want removed. If your software has an equalizer, parametric equalizer, a bandpass/stop filter or a low/high pass filter, you can actually do a lot with it and get nearly perfect results with tape hiss.
Goldwave (www.goldwave.com) has this ability. It isn't exactly free, but even the shareware version will let you perform any 100 operations you want before it starts nagging. If it starts nagging, you can restart it and the count begins anew. It is also very cheap to buy and almost as good as Audition. Especially for the price at $45. It is very powerful.
1. Goldwave's equalizer (found under the effects/filters settings at the top) has 7 bands, or sliders. Try selecting a small portion of the audio, one with both the hiss and the sound you want to keep, and start playing with the last 2 or 3 sliders and see what that does for you. You could also try the "Reduce Treble" presetting at the bottom of the equalizer window. If you get good results, try selecting the whole recording and see if it still sounds okay.
2. Goldwave's bandpass filter might also work. The "voice hum and hiss filter" presetting might do the job.
3. It also has a noise reducer. This might work, but like I said, they usually just aren't precise enough.

Hey, thanks Isaac! Your advise is very much appreciated, thank you. I shall check that program out - I tried a google search but after 3 or 4 pages of bullshit websites I gave up. I tried looking around at open source stuff but I didnt have the patience today to look more into it.
Thanks again
