Surround MultiMeter Analyzer in Logic Pro for Mac
In Analyzer mode, the main display shows the frequency spectrum of the input signal as 31 or 63 independent frequency bands. Each frequency band represents one-third of an octave or a major second. The Analyzer parameters are used to activate Analyzer mode and to customize the appearance of the incoming signal in the main display.
Analyzer parameters
Analyzer button: Switch the main display to Analyzer mode.
Top field: Indicates the maximum level. Drag vertically to adjust.
Range field: Indicates the overall dynamic range. Drag vertically to adjust.
Scale: Indicates the scale of levels. Drag the scale vertically to adjust the Range value. Changing the scale is useful when analyzing highly compressed material because it makes it easier to identify small level differences.
Sum and Max buttons: Show the summed or maximum resulting level in the Analyzer display. Sum and Max are relevant only when multiple Channel buttons are selected.
Channel buttons: Select one or multiple channels for metering. The number and appearance of these buttons vary when different surround output configurations are chosen.
Mode buttons: Determine how levels are displayed. You can choose Peak, Slow RMS, or Fast RMS characteristics.
The two RMS modes show the effective signal average and provide a representative overview of perceived volume levels.
The Peak mode shows level peaks accurately.
Analyzer Bands pop-up menu: Choose the number of bands shown in the Analyzer display. Choices are: 31 Bands (Third-Octave) or 63 Bands (Major Second).
Return Rate pop-up menu: Choose how quickly analyzed signals return from peak/maximum levels to zero or incoming signal levels. This is expressed in dB per second.
