Kdenlive seems to have at least some support for more than two audio channels (i.e. surround 5.1), as it creates an audio thumbnail showing 6 channels for such material.
When rendering however, audio is downmixed to stereo.

Does anyone know if adding such support is planned or even on the way?

It's not such a big deal as it is easy to create surround sound in Audacity (also a great Linux tool) and mux it into the video rendered by kdenlive using ffmpeg - but I really like the usability of kdenlive so it would be very nice to be able to do everything there.

Forgot to mention - if there is some interest then I'd try and create a tutorial on how to create surround sound with kdenlive, audacity and ffmpeg/avconv.

im interested

So I'll get going... will post here when I have something.

So here it is: http://userbase.kde.org/Kdenlive/Manual ... ound_Sound

I hope it is useful. Please let me know (or simply edit the page) if something is not correct or unclear.

Cheers,
Torsten
