[flac-dev] One more question on FLAC format

Dear Friends,

What does it mean "wasted bits-per-sample in source subblock" in the 
subbframe header?

Might it be, for instance, that some bits can be discarded at once 
because the maximum amplitude is such that renders them constant zero 
along the uncoded subblock?

For instance, with 16 bit resolution, if signal is less than 1/4 * 
32767, the two most significant bits are zero along the entire 
subblock, so 2 bits are wasted.

Or, rather, the bit excess between original 16 bit and encoded data?

Thank you.

Best regards,

Federico Miyara
