Dear list,
is there any specific reason why dbtorms and friends do not take dB
values <=0 as input?
From my point of view (and that of most people I know), an object
called dbtorms should do a dB to RMS conversion, e.g. convert -20 to
0.000001 in pd and not silently output zero as it does right now.
Both pd internally and high-quality audio cards can do sensible things
with numbers this low.
Kind of reminds one of the Total Ozone Mapping Spectrometer (TOMS) bug
http://earthobservatory.nasa.gov/Features/RemoteSensingAtmospher/remote_sensing5.php
which is frequently ranked among the top 10 historical software bugs
with extreme consequences: It made NASA unaware of the antarctic hole in
the ozone layer for years simply because the analysis software ignored
ozone values below a certain threshold...
So please pd developers, change this or give a good reason for not
taking lessons from history.
Best whishes,
Matthias
