My wife is finishing a Medical Transcriptionist course and needs an audio cleaner for some of the recordings. They often come with a lot of background noise or are of low quality. I'm asking your advice on what software would be best for the job. I am well aware of iZotope Rx and have used the demo for my own purposes before, but it is far too expensive and complicated for her to use. I was looking at iZotope Music and Speech Cleaner, but have heard mixed reviews about it. Is it good or good enough for what she would need it for or are there other options available? It will have to fix static, buzz, hiss, etc.
