DeNoise is a mature, well-tested, application for reducing broad-band noise, such as hiss, in uncompressed audio files. It has been developed over a period of several years. There is an extensive user manual that is part of the download package. DeNoise will not operate on compressed audio files, such as mp3, and there are no plans to incorporate such a feature.
