That's not entirely true. We do no clipping prevention on the
archos Recorders and Ondios for years...

That's relatively easy once we switch to dB volume - see my
reply to [IDC]Dragon.

Exactly. Imho there are too many options and all scaling
appening behind the scenes. If deemed necessary at all, a simple
'prevent clipping: yes/no' should be enough, scaling back
treble/bass, doing its work at the app level, with proper
indication, and for all targets (!).

See above/ other posts.
If there are no major objections, I'll commit my patch tonight.
Then we can improve upon that.
