#9 Restore clipped peaks in a waveform?
Occasionally modern albums are deliberately
mastered "hotter" than a fully normalized audio
signal; this results in clipped peaks any time the
waveform would normally be at its threshold. If the
gain on such audio is lowered, there would be room to
restore the peaks (and thereby improve playback
qualities at high volume), but so far there is no
simple way to restore these damaged areas. Could a
function be added to SOX so that the slope of the
waveform surrounding each peak could be analyzed, and
the appropriate reconstruction interpolated as
necessary?
For a sample of *severely* clipped peaks on
commercial releases, see any of Jimi Hendrix albums as
remastered for the "Experience Hendrix" label.
Sincerely,
- M.
