Hi, im looking to do some analysis work on a location and want to take readings to see how loud it is in various places today. So I'm trying to record or take readings using an app, not sure what to use but I've looked at soundbooth, and I can record stuff but not sure how to find out the average db amplitude for each recording? anyone help? Cheers, luke. edit: I believe I'm looking to find the RMS values of a recording?
