I have a project where people are talking in amateur footage. That means no lava or overhead microphone. Just digital camera. A lot of outside noise is caught.

Is there a filter, multi-band equalizer, compressor, limiter or anything I can drop on all the little fragments of audio to make the end result somewhat better? There are tools that might be able to do the job, but all tools come without any presets, so it's hard to figure out sensible defaults without a more technical background in audio. Furthermore, settings that depend on current levels (i.e. "attack") seem to be reset on every audio snippet and I don't believe I can let all the audio be treated as one channel.

Once the project is complete, a more dedicated audio software can be used. But it will take a while and a lot of exports will be made. I have no time to finalize the audio externally for every export. It would be nice if there was a way to improve the audio somewhat using clever computer wizardry.

Perhaps there is a trick, like freezing all the audio into one single clip and apply some presets on that.

    Sadly, there's very little you can do about bad source audio. As you've discovered, there are some audio processing tools that might help, but the specific settings depend on the echo patterns in that particular room in that particular location; hence the lack of presets. You can get some improvement, but it will be very labor-intensive with lots of trial and error, and the final improvement will be relatively minor.

Currently your best bet is to extract the audio of the clip before you start editing, and then importing it into Audacity, which has a great toolbox for dealing with outside noise. Once done, you can export from Audacity and back into Kdenlive.

It's a workaround, and very labor intensive. It would have been much nicer to be able to apply some basic audio filters directly in Kdenlive.

  • This tutorial goes in the same vein, and it doesn't seem to be that much work.
