STANDARD is best for ordinary recording. ANNOUNCE uses up the least
card space, and is best for recording announcements, narration, and the like.
When you are recording audio such as a narration with ANNOUNCE or

The optimal grade and mode vary according to the usage conditions,
including the connected equipment, recording source, sound quality,
time, and playback system.
The factory default settings are RDAC-Grade: LONG1; and RDAC-Mode:

yields satisfactory sound quality.
