You can use octave analysis to analyze audio and acoustic signals. These analyses exhibit characteristics similar to the response of the human ear. A-weighting filters simulate the loudness of low-level tones and de-emphasizes frequencies below 500 Hz. B-weighting filters simulate the loudness of medium-level tones and are used infrequently.
GNU Octave: Audio Data Processing
https://octave.org/doc/v4.0.0/Audio-Data-Processing.html
Octave simply treats audio data as vectors of samples (non-mono data are not supported yet). It is assumed that audio files using linear encoding have one of the extensions lin or raw, and that files holding data in mu-law encoding end in au, mu, or snd . Function File: lin2mu (x, n) Convert audio data from linear to mu-law.

Overview of Octave Analysis In an audio signal, tones one octave apart differ by a factor of 2 in frequency. As you go from lower to higher frequencies, each successive octave band doubles in width. Pitch is perceived as changing with the ratio of frequencies, not by linear increase in …

Audio Analyzers, on the other hand, typically represent spectrums with high-resolution FFT's. There are also audio measurement applications where standards require octave or one-third octave band measurements. NTi Audio provides a tool to derive octave and one-third octave band results from FFT measurement results using the FX100 Audio analyzer.
