Comment:

 It's still not working. Now astats gives no output at all for a 5s audio
 stream. Can be reproduced as follows:

 ffmpeg -f lavfi -i sine -c:a pcm_s24le -t 5 -y test.wav

 ffmpeg -i test.wav -af
 astats=measure_perchannel="Min_level+Max_level":measure_overall=none -f
 null -

 Console output for the second command line:

 C:\Users\astro\Desktop\crazy_colors>ffmpeg -i test.wav -af
 astats=measure_perchannel="Min_level+Max_level":measure_overall=none -f
 null -
