Compressing Sound for Videos
Posted in Art and Creation, Free and Open Source Software, Guides and HowTos, Programming and Technical, Ubuntu on January 30th, 2010 by doctormoI got this very useful advice from Fredreyk today, he suggests that if I do videos that I should use a process that improves the sound quality so people can hear what I’m saying. It’s the same thing that adverts use to make themselves sound louder compared to the show your watching: compression.
To do this you need to take your recorded video (in my case an ogv) and using Avidemux-gtk you strip out the sound and save it in it’s own file by going in the Audio-Menu to save the audio-stream.
Now open the audio file in Audacity mark everythink(ctrl-a) and use compression in the effect-menu i took -44db in the first slider,
but it depends on your material. Just play around, so that you stop sounding like darth vader. Save the results.
If the file sounds fine then put it in avidemux together with the video-stream (open the first point (main…) in the audio-menu and use “external”). Double checking that the sound still syncs with the video.
