Cool-Edit 2000

A much greater degree of control and more extensive features for manipulating sound files are available in sophisticated sound applications such as Cool Edit 2000 (no longer in production but currently in our lab), Adobe Audition, and Sound Forge.  The main features needed are selecting and cropping a sound as you might a photo, normalizing a sound as you might adjust the brightness of a photo, and saving the sound in a variety of formats commonly supported by multimedia applications and WWW browsers.   The Edit / Trim menu will crop (or trim) a selected portion of the sound.  File / Save as... offers a wide variety of options including .AU .WAV, .RA (RealAudio), and .Mp3. Mp3 format is widely accessible and uses an excellent compression CODEC (compression-decompression) to make file size smaller while maintaining very good sound quality.
