Octave
analysis is a widely used technique for analyzing audio and acoustic
signals. There
are many
options available for selecting bandwidth and filter banks, filter settling
times, and averaging for in-depth analysis. Both the ANSI and IEC standards
are available for octave analysis. Results can be displayed in a variety
of ways. Data can be averaged in three different modes: linear, exponential,
and peak. The exponential averaging supports slow, fast, impulse, and
user-defined modes for tracking different sound pressures and time
varying acoustic signals.
