.PK File Extension


File Type Audition Peak File
File Format File
Common? No
File 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.
Program(s) that open pk files Windows: Adobe Audition; Syntrillium Cool Edit Pro; Syntrillium Cool Edit 2000
