Short description of Wave Wash and Polish 1.1.2: Wave Wash & Polish is a batch filter designed to remove stationary and transient noise ('hiss' and 'pops') from music and other audio data stored in standard 16/8 bit sterero/mono wave files (sorry, no direct support for mp3 files). You can select a bunch of files, click on a button and go for a walk with your dog while WWP does the dirtywork. On a 2 GHz computer, WWP will process approximately 3-4 minutes of CD-quality data per minute.
