Izotope Rx: Repairing clipped audio with De-clip

Demo summary
The demonstrator uses the De-clip module to reconstruct transients and remove digital distortion from an over-gained vocal recording.
Step-by-step
- Open the De-clip module
- Adjust the threshold to a healthy range to unlimit the signal
- Click Compare to preview the changes
- Review the waveform to ensure peaks are no longer crushed
- Listen to different sections of the audio to verify the repair
- Click Render to process the unclipped audio
Tips
- Use the visual feedback of the peaks to ensure they are no longer hitting the maximum level
- Check multiple sections of the recording to ensure the settings sound great across the entire track
Highlights
“Sounds much much better. And we just rescued that vocal.”
