The best out there for a reasonable price.

Cleaning messy noise is impossible, does not matter how fancy tool one uses, but this app does a good job, as much as possible without top grade equipment. It crossed my expectations. Wind? Noise? It can clean that. The more noise to clean, the more metallic result. I just wish I could clean a clip sampling audio from another. Generally: It works like magic ;)
