Level Meter in Logic Pro for iPad
Level Meter shows the current signal level on a decibel scale.
Stereo Level Meter instances show independent left and right bars, whereas mono instances display a single bar.
To add Level Meter to your project, choose Metering > Level Meter in a channel strip Audio Effect plug-in menu or the Plug-ins area. See Intro to plug-ins. Also see Add, replace, reorder, and remove plug-ins in the Plug-ins area and Work with plug-ins in the Mixer.
Peak level values are displayed numerically and graphically. You can reset these values by tapping them in the display.
Level Meter parameters
Mode pop-up menu: Choose a display setting using Peak, RMS, Peak & RMS, True Peak, or True Peak & RMS characteristics.
The True Peak options display interpolated sample values.
You can choose to view both Peak and RMS levels simultaneously.
Target level field: Drag to set a target level. Signals above this level and below 0 dB are shown in yellow directly on the level meter(s).
Level Meter(s): Displays the current signal level on a decibel scale. The signal level for each channel is represented by a green bar. Signals (above the target level) approaching the 0 dB level are represented by a yellow bar. When the level exceeds 0 dB, the portion of the bar above the 0 dB point turns red.Peak/RMS field(s): Tap to clear peak or RMS value(s).
About Peak and RMS levels
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.
