I don't know if this type of request is allowed on the forum as I've just signed up for this specific purpose.
I have an audio recording that has some pretty major Ssss type hissing on words that start/end with an S. I did some googling, downloaded a trial version of Soundbooth and tried to do a voice enhancement on it along with normalising and some other stuff. In the end I made the thing worse! I clearly don't know what I'm doing.
Is someone able to help me by fixing this? It's a small audio clip (16mb) which is an interview. I've included a download link to it below via dropsend if anyone is keen to help me out. The interviewer is more or less OK, you can really hear the problem with the interviewee though.
