 aphasemeter outputs the audio received (with metadata injection) on its
 first output pad, and the generated video on the second, so in your case
 you were attempting to map the audio output into the video of your output
 file. The modified command below should work for you, I believe.

 ffmpeg -hide_banner -i "Test.wav" -filter_complex "[0:a]
 aphasemeter=s=hd720:rate=50:mpc=cyan, format=yuv420p [a][v]" -map "[v]"
 -map [a] -r 50 -vcodec libx264 -s 1280x720 -pix_fmt yuv420p -preset slow
 -crf 20 -profile:v main -level 4.0 -acodec aac -ab 192k -ac 2
