Adobe Audition: Using Spectral Frequency Display

Demo summary
The demo illustrates switching to the Spectral Frequency Display (Shift+D) to visualize audio frequencies as a heat map to identify specific sounds like sibilance.
Step-by-step
- Open the Waveform view
- Press Shift+D on your keyboard to toggle the Spectral Frequency Display
- Identify speech by looking for the heat map patterns in the low and mid-range frequencies
- Locate sibilance or 'S' sounds by finding red blotches and peaks in the higher frequency range
Watch out for
- You must be in the Waveform view for the Shift+D shortcut to work
Tips
- Use the spectral view to identify background noise and audio problems that are invisible in the standard waveform view
- Remove identified sibilance peaks later using a de-esser tool
Highlights
“spectral frequency will help you to see a lot more that you can't necessarily see in the waveform view”
