if possible, I need to see something like VU meters audio levels to check if the peak levels of audio CH1 and CH2 (that contain the mix of the audio CH3 and CH4) is -12Db.

Or howevere to see the levels

is there a way to have an audio levels VU meter - thanks

thanks but is VLC, is there a way to see audio levels overlayed to video?

Don't most good video editors have a sound level display?

@Treetops, but that requires using a good editor, which, knowing the OP's history, is anathema.

Use avisynth under VLC? You can overlay 'ebur128' and eventually 'showvolume' on top of your video in ffmpeg.

In AviSynth, Histogram("audiolevels")
