Some output of the FFmpeg HDCD filter's analyze_mode.

The track is Neil Young - Red Sun, from Silver & Gold.

Track Option setting Description
1 analyze_mode=off HDCD decoded
2 analyze_mode=lle LLE gain adjust levels in each sample
3 analyze_mode=pe Samples where PE occurs
4 analyze_mode=pe:force_pe=true Original sample was in the -3dBFS range (should match above when PE is permanent, but maybe not when it isn't)
5 analyze_mode=tgm Samples where the target_gain was ignored because it didn't match in both channels
Not shown analyze_mode=cdt Samples where HDCD decoding was active (whole track in this case)
