None of the blind men are really right and none are wrong. In the
meantime no coherent picture of the dBFS elephant has emerged and more
disjointed statements are made on the topic.
It seems to me if you realise the Bell or dB is a RELATIVE LOG term of power
(and it's constituents) ratio's with no absolute UNLESS defined as a subset,
(eg dBv, dBu, dBm etc) then asking for a SINGLE absolute point of reference,
or single definition, is simply asking for the impossible.
dBFS is simply the *Full Scale* point of ANY system so defined. IF you want
it to mean anything specific, you must define it as such.
MrT.
Pretty much. As long as the units of the reference and the measured
value are compatible it's just an equation to plug into.
