 +Octaves are defined as a doubling of magnitude.  Moving a single octave can move from a frequency of 4 Hz to 8 Hz or 1000 Hz to 2000 Hz.  Octave analysis often breaks Octaves into bins 1/N times.  Octave filter displays responses in frequency bins.  Passband filters are applied to time stream data and the resulting magnitude of frequencies are overlaid into single response to show strength of signal by frequency octave.
