Please add any idea / comment / code sample here

I (kimaidou) copy/paste the comments I had on the community mailing list

change framerate + mono

I think 44100 Hz is overkill for something like this. 8 kHz ought to be enough and would save a lot of disk space. I would have also suggested a mono recording, but I'm not sure that is supported.

--> the solution is just the man :) man page

enable job control

You should use "kill %1" instead, this will only kill the instance you just started (and TERM is the default). For that, you need to enable job control (set -m) + remove the &

Result :

#!/bin/bash
# Exit on error
# Enable job control
set -em
zenity --question --title="Voice-note" --text="Click Validate to START recording"; gostart=$?

if [ "$gostart" = 1 ]
   then
       echo "Operation canceled"
       exit 1
   else
       echo "Recording..."
fi
alsactl -f /usr/share/openmoko/scenarios/voip-handset.state restore
arecord -D hw -f cd  -v -t wav ~/rec-$(date +%Y-%m-%d-%H-%M).wav &
zenity --info --title="Voice-note" --text="Click Validate to STOP recording"

# Kill arecord
kill %1
alsactl -f /usr/share/openmoko/scenarios/gsmhandset.state restore
zenity --info --title="Voice note" --text="Your voice-note has been recorded"

#END OF FILE
