Hello
I'm wanting to batch process a bunch of wav files, normalising them all
to -0.3 dBFS.
that's high! you will almost certainly get distortion in the analog
stages of cheaper playback equipment with a signal that hot. think
inter-sample peaks.
I thought I could do this with
normalize/normalize-audio, but it doesn't
look to be possible. The man page suggests that simply analysing the
file and raising the level so the loudest peak is 0 dBFS isn't
normalising, which is news to me:
depends. that's peak normalisation. what you probably want is loudness
normalisation, which adjusts the levels so that the perceived loudness
is constant across tracks.
in a presentation i heard recently, the presenter played a metallica
single, in direct comparison to pink noise at full scale. the metallica
mix was significantly louder. go figure...
" --peak
Adjust using peak levels instead of RMS levels. Each file will be
adjusted so that its maximum sample is at full scale. This just gives a
file the maximum volume possible without clipping; no normalization is
done."
that is a funny definition of normalisation.
That would be okay, except I want them normalising to
something other
than full scale.
Is there a quick and easy way to do this?
like julien suggested, use a standard peak normalizer and then attenuate
by 0.3dB )(if you are sure that's what you want to do).
