[BC] FM Band other used for 19 kHz.

[DANA PUOPOLO]

I agree that 5% is but 1/2 a db, but I'd rather use it to have someone say,
eliminate a composite clipper that they're using 1/2 db of clipping with....

Of course, they'd likely just keep the clipper and turn stuff up too.

quite
a lot of loudness - if loudness is what you really want.
