If your distribution ships with a different version, it may not get detected, or may not work correctly.Ĭaution: Audacity supports FFMPEGs libavformat in version 55 (all Audacity versions), 57 and 58 (Audacity 3.1+) and 59 (Audacity 3.2+).
What is FFmpeg for Audacity Which files can FFmpeg for Audacity open Get the answers from the file experts at. button to obtain the correct library for your operating system. So how can I reproduce the output I get from Audacity "Truncate Silence" filter with ffmpeg and remove all silence parts from audio ?Įdit: The output from silencedetect filter is correct: ffmpeg -i input.wav -af silencedetect=0.2:n=-45dB -f null - detects exactly what audacity detects.You can also choose Help > Diagnostics > Show Log. Searching on the internet only lead me to what I already do. This will yield to what I want (ie an audio with no silence part remaining): In Audacity I will use "truncate audio" filter and choose the above parameters to detect silence and in the action part I will choose to truncate to 0. I am using the following ffmpeg command to remove silence part ffmpeg -i input.wav -af silenceremove=stop_periods=-1:stop_duration=0.2:stop_threshold=-45dB output.wav because I understand from the doc that it will remove all silence parts longer than 0.2 s (silence being below -45dB).īut I get that where silence part has only been reduced to around 0.1 wheras I want it to be 0 (no remaining silence). I want to remove completely silence parts from wav files with ffmpeg.
