At the next LAC I'll present an app that calculates * true peak * max momentary loudness * max short-term loudness * average loudness * loudness range for a file, all to the EBU R-128 standard. Loudness is based on RMS after some filtering. I could add a switch to bypass the filter and R-128 specific averaging (which is not just averaging). But if you need the RMS values as a loudness estimate, then the full R-128 algorithm will provide better results than straight RMS. It should handle any file that libsndfile can read, this includes FLAC. First release in a month or so, ATM only the real-time version (jack input, GUI) is finished.
