Wanted to try and "restore" a clipped piece of audio in Cool Edit Pro, so tried out a search for doing so in Audition and found this discussion which may be useful. In my case, just changing the sample depth 32 to 16 was enough for me. But useful for reference:
- Convert to 32 bit
- Normalize to 50%
- Use Chebyshev bandpass 18th Order, 4 Hz to 22.5 kHz.
