20*log10(2^24) = 144.5 dB
though if you consider that 1 bit is taken up for the sign (i.e. + or -
) then
20*log10(2^23) = 138.5 dB
( Note how 6 dB = 2x )

I discoved that this is for the meter only, and the minimum that
cinelerra forces to -Inf dB is -40 dB!! See cinelerra/virtualanode.C
which contains:
if(fade_value <= INFINITYGAIN) fade_value = 0;
and INFINITYGAIN is defined in guicast/units.h as:
#define INFINITYGAIN -40
...
Prior to discussions with j6t on IRC, I had been considering setting
the "INFINITYGAIN" as a property of the current project (thus 24 bit
audio freaks could specify huge attenuations).
I would like to know, with reference to authoritative sources, what the
canonical dynamic range for 24 bits sampling is. Is it linear, like
16bit?
