Hi - I originally posted this in uk.comp.sys.mac and was recommended to
try here as well.

Does anyone know if there's a utility to get average decibels from an
audio track, where 'an audio track' could mean wav, aif, mp3, or mp4
(as in I'd convert to whatever's necessary)?

Context: am trying to prepare a number of different music tracks to be
at the same level. It's my music so I have control over settings etc.,
but I've now listened to these so many times that I'm finding it hard
to be independent and quantitative about the situation.

What would be ideal would be a utility that could scan and do
min/max/avg. Icing on cake would be if it could also do histograms
(i.e. "of your five minute track, 90% is spent at this decibel range
with 5% being significantly more quiet and 5% being significantly more
loud). For cherries on top of the icing, it would be able to aggregate
these readings across multiple sound files (i.e. feed in the whole
album, eliminating the manual step of me trying to correlate the
results).

Any ideas?


Cheers,
Ian

Orban, the sound processor people used by just about every radio
station have a desktop sound meter for PC or MAC. One of its meters is
a pretty good perceived loudness meter. Give that a go, and you may
find it tells you what you need to know, even if you then have to make
the changes yourself.

And it is free.
