Most of the so called normalising that at least windows has are far from
ideal. assuming they try to preserve the original dynamic range, the tracks
with lower dynamic rang seem to be quiet. I know one can squash the dynamic
range of the tracks to all sound as ghastly as one another as radio
stations do this all the time!

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
