Meter

The Meter view can display three different kinds of levels:

  • Peak

  • True Peak (as defined by ITU-R BS.1770-4)

  • RMS

Each type of level shows the values per channel. For more information about speaker configurations and channels, refer to Understanding Bus Configurations.

The color of the meter is:

  • green under -6 dB

  • yellow from -6 dB to 0 dB

  • red over 0 dB

The meter data source can be synchronized with the currently playing objects or, when a profiling session is present, with historical values. When the meter is showing the profiling session history, use the LIVE button on the Wwise toolbar to return to current values.

For more information, refer to Monitoring the Signal Level.

For details on the Meter Instance, A, B, C, or D, refer to Understanding Selection Channels and Meter Instances

The Meter displays the following elements:

Description

Peak

Peak metering measures the maximum or minimum values of a PCM signal for a very short period of time. (Units: dBFS)

True Peak

True peak is an estimate of the maximum peak of the digital signal in the analogue domain. This value is useful when making sure the digital to analogue converter is not saturated. (Units: dBTP)

True peak is implemented on ITU-R BS.1770-4 specifications.

Root mean square (RMS)

The RMS level is measured with the peak meter values and does an average over a very short period of time.

3D Meter

The 3D Meter mode provides a 3D spherical representation of the directionality of an ambisonic signal. It calculates the Peak level at every virtual speaker position on the sphere. A heatmap representation is then generated from each of the positions on the sphere. The 3D Meter mode is currently only available on busses that have an ambisonics bus configuration.

For more information regarding the 3D Meter mode, refer to 3D Meter.
