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.


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 :

  1. !/bin/bash
  2. Exit on error
  3. 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..."

  1. Kill arecord
