    Hello,

   I am looking for information on algorithms that can be applied
to digitized sound data that yield psychacoustically relevant
measures of "average sound level" and "dynamic range". 
These measures would be computed at specified intervals
over the duration of the sound (say at 200 ms intervals).
"Average sound level" should yield a measure of the overall
sound intensity over a given interval and "dynamic range" 
should yield some measure of contrast between loud and
soft sounds over some duration.  If anybody knows of relevant
literature on this I'd appreciate it if you emailed it to me
or posted it here.  Thank you.
