2 septembre 2019, par SomeoneElseI am running a Docker instance of Cocalc on a Ubuntu 16 server. Everything seems to be working but I am trying to debug why
sage -pip install --user ffmpeg
did not make the "OSError: Error: ffmpeg does not appear to be installed.

Completely remove high frequencies from wav file with ffmpeg
21 septembre 2021, par Melvin BenderFor my speech recognition project, I'd like to completely cut off frequencies above 5000Hz on my wav files using ffmpeg.
I understand there is a lowpass filter for reducing frequencies above a certain value :


ffmpeg -i original.wav -af "lowpass=f=5000" lowpass.wav



However when I check the spectogram, it seems like frequencies above 5000 have been reduced, not completely cut off


Voice sample with 5000Hz filter


How can I completely cut off frequencies with ffmpeg ? Any other software is also fine.
