Wow! I never thought of using ffmpeg for this. I especially like the way you can tweak parameters that compute the "average RMS" adjustment desired. Does this always re-transcode the file (granted "re-transcoding" an uncompressed audio file should be close to lossless), or will it simply losslessly (and quickly, and reversibly) set a single "track gain" parameter to a file format that supports such a thing like the way "mp3gain" does?

I had to do some audio normalisation (loudness/RMS) on a batch of videos recently. I used ffmpeg to automate the process but you have to be careful what you're doing as you can overcook it. _______________________________________________ Rivendell-dev mailing list Rivendell-dev@lists.rivendellaudio.org http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
