Strange Sounds

[Paulus]

I can record and playback.
BUT: When I try to clean-up the recording from clicks (with standard settings) I get a totally distort sound (as if it is played back through a long plastic tube). I was able to normalize the sound and to split the sound into tracks, but no clean-up what so ever! Anyone an idea how to solve this problem

How are you trying to "clean-up the recording from clicks"? Are you using "Click Removal" or "Noise Removal"?

Both of these effects are "destructive" in the sense that they are making permanent changes to the audio. These effects have to try and guess what is noise and what is music - tweaking the parameters will help the effects "guess" with better accuracy.

For both of these effects you will need to try adjusting the settings to achieve optimum results, and it will require a little experimentation. Try working on a small sample of your recording before applying the effect to the whole track.

Hi there Steve! I used the "Click Removal", and, because I already worked with "wave corrector" under wind before, I knew to be careful. So when I tried to correct a peace of my recording, I made the settings even less sharp then the original settings of audacity, but the effect is in one case zero, when I give just a tiny little bit more effect, the result is disastrous. Only way I found out to correct something, without corrupting the whole file, is to search for the clicks in maximum zoom and correct it by hand, with the pencil-tool, but that's a hell of a job to do for a peace of ¾ of an hour.
I found in the repos of PCLinuxOS the tools GWC and Kwave, which seem to be something like wave-corrector, I'm going to give them a chance. I'll let you hear about it some time.

There is another tool available in v.1.3 called repair - you would use it in a similar way to correcting with the pencil, except that it makes the adjustments to the samples automatically. The procedure is to zoom in very close on a click and select the click, then from the effects menu select "Repair". It will still take ages on a long file with loads of clicks, but it is considerably quicker than using the pencil, and it works very well. (very handy if you just have a few loud clicks).

The other thing I was going to suggest was "Gnome Wave Cleaner", but you beat me to it

I used to use the Repair function in 1.3 which Steve suggests - it worked extremely well, but as he also says takes a lot if time.

So I now use a software tool (ClickRepair) see this thread: http://audacityteam.org/forum/viewtopic.php?f=28&t=1994
