Dear Walt et al,
This is a question that has been plaguing me. I record in stereo from a mon=
o
microphone so that if I have a sudden increase in volume from the subject I=
am
recording the high trac will "Clip" or "burn out", but the low trac will no=
t.
However, I have noticed that when the "high" trac is fine and not burnt, th=
e
low trac does not seem to have the same quality. I use an HHB Portadisc MD.=
So, my question is...at what -dB will the machine start receiving too littl=
e
data to capture all the sound. When something is recorded at -60 dB once it=
is
equalized with something recorded at -10 dB will they sound the same (and l=
ook
the same in a spectral analysis)? My experience says NO. So, there must be =
some
range of -dB where the machine is just not getting enough data to capture t=
he
sound. Any idea what this -dB figure is?
I know that the above sounds pretty unscientific and unsophisticated, but
please be patient with us scientifically impaired recordists!
My best,
John
