The current peak values are displayed numerically, superimposed over the graphic display.
You can reset these values by clicking in the display.
The Level Meter can be set to display levels using Peak, RMS, or Peak & RMS characteristics.
Choose the appropriate setting in the pop-up menu below the graphic display. RMS levels
appear as dark blue bars. Peak levels appear as light blue bars. You can also choose to
view both Peak and RMS levels simultaneously.
Peak and RMS Explained
The peak value is the highest level that the signal will reach. The RMS (root mean square)
value is the effective value of the total signal. In other words, it is a measurement of the
continuous power of the signal.
Human hearing is optimized for capturing continuous signals, making our ears RMS
instruments, not peak reading instruments. Therefore, using RMS meters makes sense
most of the time. Alternatively, you can use both RMS and Peak meters.
Tuner
You can tune instruments connected to your system with the Tuner utility. This ensures
that your external instrument recordings will be in tune with any software instruments,
samples, or existing recordings in your projects.
