How to extract Sound pressure from wav file?
I have to extract the sound pressure [db (A)] over time to determine
the average over 5 seconds. This I must be able to automate in order
to apply it to about 2000 sound files.
The software DIAdem , LabVIEW and MatLab are available. Another
freeware would be no problem.
Does anyone have an idea for it?
Regards Frank

You are asking us is like how to determine the depth of the ocean by looking
at the waves.

That can be done given sufficient [possibly infinite] other information.

Love how the pricks all do that.

Your software needs upgrading, you are not even close to passing the Turing test.

Do you have any reference points or any samples? Were they all recorded
with the same reference levels? Can you prove it?
Do you know anything about how the files were created?
