* Equipment need to have good quality microphone, headphones
and multiple producers may use headset splitter * Timing need to
estimate preparation time (i.e. writing first draft of script to
editing the final draft of script) but the recording time could be
quick (i.e. simple recording) or long (i.e. adding special effects
such as echoing, adding background music, fading out at the end,
etc.)
