211 representation on a dB amplitude scale and linear frequency scale.
462 However, floor vector values can span \~{}140dB (\~{}24 bits unsigned), and
463 the audio spectrum vector should represent a minimum of 120dB (\~{}21
466 $-140$dB, it must be able to span 0 to $+140$dB. For the residue vector
467 to reach full scale if the floor is nailed at 0dB, it must be able to
468 represent $-140$dB to $+0$dB. Thus, in order to handle full range
469 dynamics, a residue vector may span $-140$dB to $+140$dB entirely within
470 spec. A 280dB range is approximately 48 bits with sign; thus the
