 not sure if this is a bug or expected behavior. for an audio file that
 only contains silence, this command only logs the beginning of silence (–
 no end and duration):
 {{{[silencedetect @ 0x7ff3977000c0] silence_start: -0.00628118}}}

 command:
 {{{ffmpeg -i silence-31s.mp3 -af "silencedetect=n=-50dB:d=1" -f null -}}}

 ffmpeg version:
 {{{3.4.1}}}
