Comment (by Danny Weijermans):

 thanks for your relevant link!
 yes, but I'm not using a 'lossy' audio fileformat.
 it's a 'firm' wav file, I have put an very short wav file (s.wav) example
 as an attachment.
 my command line (which works on longer wav files) for example:
 ffmpeg -i /Users/disjt/Desktop/s.wav   -filter_complex
 "showwavespic=s=640x120" -frames:v 1 output.png
 if  /Users/disjt/Desktop/s.wav points to a longer wav file it's working
 perfectly.
 if it's a shorter than 200msec it's not working..
