If you want to see the effect of the normalization in FFmpeg you still
get a lot of messages in between. A filter like

ebur128=volnorm=I,volume=metadata=lavfi.r128.volume,ebur128

ends with a report containing the loudnesses after and before the
normalization (in that order, but who cares). Is there a way to suppress
the intermediate messages and show only the summary? Something like

ebur128=volnorm=I,volume=metadata=lavfi.r128.volume,ebur128=quiet
