Actually, some sort of "normalisation" process would be handy, and could be
done in a similar way to the proposed defragmenting methods.
- Scan through a track (say sample every 3 secs) - at the loudest point,
mark it [my CD player has a "Peak Search" button that does this] and work
out what increase is needed to bring this up to 98% (or some other value)
- Read 20 secs (or so) from the disc to the buffer, pull it all up to the
new volume level and write back to the disc
- Repeat till done, with some clever trickery to overlap samples so it
doesn't get disjointed.
Quiet-sounding albums could be done the same way, with a scan of the whole
disc before deciding on a change value.
I'd certainly find it very handy - I like to make sure compilations are all
about the same volume to save on changing the volume all the time, so if I'm
feeling fussy I'll record each track individually, doing a peak search
before recording then setting recording level for each track. If I could
record it all, then let the deck whirr away and do it all for me it'd be
cool :)
