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
