In the showwavespic filter, the option filter=average shows a larger
amplitude than filter=peak. That can't be right. The average can never be
larger than the peak.
Can be reproduced by comparing the output images:
ffmpeg -f lavfi -i sine=100:b=2 -t 0.2 -y sine.wav
ffmpeg -i sine.wav -lavfi "showwavespic=filter=average" -y average.png
ffmpeg -i sine.wav -lavfi "showwavespic=filter=peak" -y peak.png
