We're just trying to help. but you don't help, not answering on subject. I know all what you say, but it's too long for me to make it right now, I simply don't have the time to fine tune the audio track - the original band sound is already not that good, for reason out of my reach. thanks for your help anyway jdd -- http://dodin.org

I do it all the time (although using Ardour not Audacity). two things: * why use an other editor when kdenlive (seems to) already have the tool, apart if you say the tool is broken Well it's not broken per se, just incomplete. It's a well known drawback that Kdenlive currently lacks a master bus, for example. This means that while you can drop a compressor on a track you cannot make it compress the mix of, say, a video track with the voice on it plus backing track with music, thus you cannot guarantee there is no clipping of the audio in the end. * there is a much simpler workflow when I happen to have a source already cut (for example if I made only short clips), I use this script ... #!/bin/bash rep="mp4-hd" ; mkdir $rep ; for a ; do b=`echo "$a" | cut -d'.' -f1` ; ffmpeg -i $a -af loudnorm -ar 44100 -b:v 12000k -movflags faststart $rep/$b.mp4 ; done exit notice the "loudnorm" option. Again, that depends on the task, it won't help you if you mix the audio from the several clips in a complicated way. Also, I'd rather -c:v copy for the ffmpeg and do the whatever processing with reencoding of the audio before cutting in Kdenlive if the indention would be to cut with the video files where audio tracks would be pre-processed somehow.

In my opinion, non-linear video editors like kdenlive are best used to composite several different clips together, not perform major processing on them. I use it mostly to cut the 4 hours track in clips a song long (or a medley). Right now I only use "normalize" as effect. I used to do more like on this (2011) clip: http://dodin.org/piwigo/picture.php?/139382-20110617_01_rolling/category/4812 but I'm aging and if I still use two or three cams to make the take, I rarely mix them (it's mostly as backup) If you've got an audio file of someone singing, I would recommend fixing it first in audacity, then importing the fixed clip into kdenlive. I know I can do this, but it's a lot of works. Asking kdenlive to make HD clips from the source on a decent machine (i7, 16Gb ram, ssd) takes around three time the gig time (and the gig is around 4 hours), only counting machine time :-( First, you'll want to level-compress it, not merely normalize it. I recommend Chris' Dynamic Compressor, which can be found at https://github.com/theDanielJLewis/dynamic-compressor-for-audacity . You can put the compress.ny file into your Audacity plugins folder. Normal audio clips can use the default compress ratio of 0.5. For speech and vocals, I tend to boost that to 0.75 for better results. Hope this is helpful. sure it is, thanks jdd -- http://dodin.org
