Audio silence detector. then mux the audio using another input argument for ffmpeg as ffmpeg -i video. OK, I Understand. A live concert could be broken down into songs so that you can burn it on a CD, or an interview can be separated into thematic sections. ) All you need to know is the start time and duration of the section you'd like to extract. You could do something crazy like keep a silence. Adjust this to match your presentation style. Features and highlights. How can I trim this silence from the captured audio programatically using any algorithm? There is a lot of background noise in the audio captured, please suggest me any way prefereably algorithm to reduce the background noise? Thanks in advance, Regards, Suresh G. Can you trim the files from withing OBS or by using a program like VLC? I just need to trim off the ends of some files to make them shorter.
