Do you have a recording or audio file that needs cleaning up? Lecture recording that has too much background hiss or noise, bad recording with fuzz/pops or clipping on it, or something which has deteriorated. I can help you. I have all the necessary software (and it is ridiculously good) and know-how to clean up pretty much anything, and bring out the element that you are wanting the most. I am more than willing to give a free review of a short(for speed) audio file, if you are unsure whether it is treatable etc. I can have a listen and get back to you about feasibility.
