i am not a sound person so i don't really know what i am talking
about...
but i was instructed to make sure that the average dB level fo a piece
of audio (in aiff format) was at -12 dB.
i am using a macintosh and am wondering if there is a piece of sofware
which would allow me to figure out my current average dB level and
alter the dB level to -12 if necessary.
thank you for any input.
i have audacity and bias peak currently, though i know how to use
neither. but i am hoping one of these programs might do the trick.
thank you again.

on many types of audio programs the meters are peak reading. when setting
levels with a steady sine wave signal it often works out that -12 dB is a
good place to adjust to. when recording the level meter then look "normal"
and pretty much says out of the "red" i.e. avoids clipping.

the "average" level should be dependant on the type of material being
recorded. i.e. classical music has a large dynamic range and should be
recorded mostly at very low levels so that when a loud passage comes by it
is not clipped, limited, compressed, or distorted.

thank you for the reply.
however-the music is already recorded.
what the deal is-i have a music video in two parts-the video and the
sound.
i am supposed to be giving the music video to a company and they have
some specifications about the sound.
one of their specifications for the sound is that "the audio have an
average decibel level of -12 dB".
their other specification is that the sound have a sampling rate of 48
khz.
so i have an aiff file from the band (which is of course, 44 khz).
i am the one dealing with getting the video ready for the company so i
have this uncompressed sound file and i am trying to make sure the
average decibel level is -12 dB and if not, fix this problem.
the video will be mastered on to DVD by the company for use on i guess
television.
thank you.

Book two hours at a local studio and save yourself some trouble.

Use peak to do this. I have heard that DVD sound needs its peaks to be
at -6, so if you normalize (under DSP menu) to -6 in peak, chances are
the average level will fall into place. Then, do a sample rate convert
(also under the DSP menu). Finally do a save as or save a copy as, since
you don't want to change your original files in case you need to go back.

The latest version of Peak is supposed to have an RMS Normalize function
that should do the trick. [I'm still using a back rev, so I haven't
tried it.]
