BumpUp.exe quadruples the size of a wave file, making it sound four times lower. This allows you to hear the super high frequency content in your music and work with it. When you are done filtering it you can then run BumpDown to return your masterpiece to its original speed. Desnap eliminates loud unwanted clicks from digital music without sacrificing any brilliance. This is not a filter. It scans wave files for "snap events" and fixes them.
