Description

Contains the visual representation of an audio waveform for a corresponding audio file; generated automatically by Audition and Cool Edit Pro when an audio file is opened; saved in the same folder as the original audio file.

By default, peak files are generated for all audio files opened in Audition 2.0. This speeds up the waveform display process since the waveform only needs to be generated the first time. You may turn off the automatic peak file generation by choosing "Edit→Preferences→Display." Then deselecting "Save Peak Cache Files."

Adobe acquired Syntrillium in May 2003 and rebranded the program Cool Edit Pro as Adobe Audition.
