Waveform Editing - Audition

Waveform Editing

Waveform Editing is for editing single audio files- .mp3, .wav, .aiff, etc. It is a form of Destructive Editing. When changes are made to the waveform file they also permanently alter the original file. Waveform Editing is useful for a Fade In or Fade Out, Normalizing, simple Editing, and converting sound files from Stereo to Mono. Waveform Editing provides a visualization of the audio file's Sound Waves.

Open a File

1. Choose the Waveform Mode at top left of the Audition Panel.
2. Under the Audition Main Menu select File > Open File > and select your audio file. PKF files are visualizations of the sound waves. Do not import these files into Audition.
3. The audio file should appear in the File Window with its name and duration.
4. The audio file can be dragged from the File Window into the Waveform Timeline to begin editing.
   1. If the audio file is a Stereo Recording the Left Track will be displayed on top of the Right Track.
   2. Each track can be independently disabled by clicking either the L and R or 1 and 2 boxes corresponding to each track on the far right end of the timeline.
