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.

Normalize

Normalizing your audio file is the application of a constant amount of Gain to an audio recording to bring the average or Peak amplitude to a target level.

To Normalize your audio file:

1. Under the Audition Main Menu select Favorites > Normalize to -0.1dB or to Normalize to -3dB, depending on how average peak amplitude change is necessary.

Editing

To isolate a Specific Clip from larger audio file for editing:

1. Hold down the right cursor on the mouse, dragging it over the desired audio for the new clip.
2. Once the desired clip is highlighted in the Waveform Timeline, go to the Audition Main Menu and select Edit > Copy to New
3. The Waveform Timeline should now only display the specific clip.

To edit Volume of a Specific Clip in a larger audio file:

1. Hold down the right cursor on the mouse, dragging it over the desired audio in the Waveform Timeline.
2. Once the desired clip is highlighted, use the Amplify panel that appears on top of with clip. Before any changes are applied the icon will read +0dB.
3. By dragging the mouse over this icon, the amplitude can either be increased, by dragging to the right, or decreased, by dragging to the left.
4. This change in Amplitude will only be applied to the highlighted selection.

To edit Volume of an Entire Audio File:

1. Go the Audition Main Menu and select Effects > Amplitude and Compression > Amplify.
2. In the Effect Amplify Window change the Amplitude Meter dragging the mouse to either increase or decrease the dBs.
   • It is best to raise or lower a file's amplitude in small increments.
3. Once you have completed the desired change in amplitude select Apply to apply changes to entire file.

Stereo to Mono

Converting Stereo to Mono takes the audio recording from two channels to one channel.

To convert from Stereo to Mono:

1. Under the Audition Main Menu select Favorites > Convert to Mono
