My soruce is an old vhs-tape with very low audio level, so I normalized it to hear the speaking persons better, but now I have terrible audio noise. is there an audio-filter to remove the noise?

Re: Audio noise removal
Never done this in Kdenlive, but I assume there is an effect for this, just check the audio effects list.
If not, you might want to try running the audio through Audacity, I know their noise removal filter is quite good. You could then join the audio and video back up in Kdenlive

You can't, moorsey didn't mean it that way, just extract your audio from the video to an uncompressed format, run it through Audacity, and drop it back into kdenlive as a second audio track?

Re: Audio noise removal
Thanks that's the way I am doing it. THis means you have to cut before and at the end you export and import the audio. Bad luck, if you forgot something to cut, than the audio export and import starts again.

Re: Audio noise removal
sorry I don't quite follow you, currently do you use kdenlive to extract audio from the edit? It's simple to do the audio extract from the source video files with ffmpeg or similar on the CLI or batch script outside of kdenlive, process that in Audacity and then import the 'cleaned' audio into kdenlive complete as a source clip, to sync with the unedited video stream?
But have you also investigated the LADSPA plugins, there may well be suitable filters already available within kdenlive to do the job.

Re: Audio noise removal
Audio edit from the source isn't that easy. I have hundreds of small source clips, which have been cut automatically be scene-detection.
How can audio be run through Audacity or Ardouzr direclty?
