vertical bars that show the level at the current playhead position. The left bar shows the
levels for the left audio channel and the right bar shows the levels for the right audio
channel. As you play, the meters change to indicate the changing audio level.
Peak indicators
Peak indicators appear at the top of the meters. These small lights illuminate red when
the volume exceeds acceptable levels (called peaking). They remain red for a short time
after the peak occurs.
