In
Cinelerra, there is a configuration setting for how low you want the level
meters to go.
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
I proposed on the IRC to change this to -96 to account for 16 bit audio,
(the most people are likely to work with). j6t and i agreed to this
idea, but more recently, I have realised that people loading old
projects with levels of -40 dB would suddenly find that the audio
signals will not be forced to -Inf dB any more, and thus they will hear
sounds.
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). j6t advised against this
(micromanagement), but on considering the problem of old projects
issues, I wish for this to be re-considered. What do people think? I
personally see the idea of having a per-project minimum dB as good, both
for backward compatibilty, as well as for professionals..
I was going to also make the default for new projects independent of the
last project, (i.e. the default for a new project would always be -96 dB.)

What numbers have I to write if I want silence when the white fade line
is at the bottom margin of the track and a slightly too loud sound when
the line is at the top margin?
The defaults should be like that already.
