R128

This application measures loudness according to EBU R128 with ffmpeg and ffprobe.

You can send video or audio files to the app. Channel layout inside video can be mono or stereo. But mono files will temporarily merge to a stereo file at first. If number of mono tracks is uneven it will return an error.

Send a file to R128. (If opening with double click you get a file select window.) If there are more then one stereo or two mono tracks you get a popup to choose the tracks.

The choosen tracks are first extracted to %temp% as output.wav in 24bit and 48kHz. Progress is shown in the gui. Then it measures this wave file. If ready you can copy the result to the clipboard.

Output.wav will stay at %temp% until overridden. So you can use the app as an audio extractor or audio converter too.
