ok and i got always a bad audio so i have used arecord like someone has suggested on launchpad
https://bugs.launchpad.net/ubuntu/+source/recordmydesktop/+bug/339648
so i have created my personal script to screen grabbin and i got it ! now i can do my screencast with very good audio and i can denoise it automatically.
you can find it here
INSTALLATION
Install this:
sudo apt-get install oggz-tools recordmydesktop vorbis-tools sox libsox-fmt-all
Download and save it on :
/usr/local/bin/arecordmydesktop
if you don’t want install kdialog then you should create a settings file like this in this location
$HOME/arecordmydesktop.txt
:
Format for video file: ogv
Video L Size: 1280
Video H Size: 800
Video Bitrate: 1000
Audio Bitrate: 192
Frame for second: 25
Frame for second recordmydesktop: 15
Sampling Rate: 44100
CPU(dual core = 2 ): 1
Mencoder profiler for lavc: None(faster)
Mencoder profiler for xvid: None(faster)
Mencoder profiler for h264: None(faster)
**EDIT:
jaunty version 0.0.6
Karmic re-version 0.0.7 (oggz-merge instead of oggzmerge…wth…)

DENOISE FUNCTION
###################
in order to use this function you have to record some
seconds of silence (\"perfect silence\") in this file
$HOME/noise.wav
typing this :
rec -c 1 -o $HOME/noise.wav
then the script will do automatically the rest
anyway here some stuff (you should use : SoX v14.2.0)
#############################################
SOX denoise function ; generating noise profile
##############################################
sox -c 1 $HOME/noise.wav -n trim 0 2 noiseprof $HOME/speech.noise-profile
#############################################
SOX denoise function ; denoise
##############################################
sox -c 1 INPUTFILE.WAV OUTFILE.wav noisered $HOME/speech.noise-profile VALUE
value shoul be 0-1 (default 0.5)
i have scaled to 1-10 because i don't want write 0. stuff
you shouldn't denoise with >0.5 (in my so >5 for arecordmydesktop)
** note: -c 1 means 1 channel if you record with 1 channel and you try to use
2 channel you could get sox get this message
line 173: 22562 Segmentation fault sox \$tempnameaudio \$tempfolder/temp.wav noisered \$HOME/speech.noise-profile \$1
so please make sure you used 1 channels
