Averaging Settings

These setting control how the spectral data is averaged.

The averaging algorithm is equivalent to that of a standard Sound Level Meter (SLM).  The average speed controls the spectral averaging period and decay time as follows:
  • Off - no averaging is performed.
  • Fast - computes a running average with a decay rate of 32 dB/sec.
  • Medium - computes a running average with a decay rate of 20 dB/sec.
  • Slow - computes a running average with a decay rate of 4 dB/sec.
  • Forever - accumulates the data for as long as the analyzer is running. 

    Notes:
    The averaging speed can be modified while processing by using the "Averaging" controls on the sidebar.
