Setting automatic level control (ALC)

You can set the automatic level control (ALC) used during micro-
phone input.
When ALC is on, the input level will be adjusted automatically in
response to the input audio.
Using this function, the recording level is automatically
increased when the input sound is too quiet or decreased when
it is too loud. This function is useful for recording meetings, for
example. In this mode, the recording level cannot be changed
manually.
