I have two pipelines

!gst-launch-1.0 -e filesrc location=video.mp4 ! decodebin ! audioconvert ! audioresample ! rganalysis ! rgvolume ! lamemp3enc ! xingmux ! filesink location=normalized.mp3

!gst-launch-1.0 filesrc location=video.mp4 ! decodebin ! audioconvert ! audioresample ! lamemp3enc ! xingmux ! filesink location=normal.mp3

When i open resulting audio with audiacity resulting audio files seem to be the same.
