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.

This chapter describes the signal processing and fast Fourier transform functions available in Octave. Fast Fourier transforms are computed with the FFTW or FFTPACK libraries depending on how Octave is built. fft (x) fft (x, n) fft (x, n, dim) Compute the discrete Fourier transform of x using a Fast Fourier Transform (FFT) algorithm.

Whether you are working with audio or sensor data, deep learning networks, such as convolutional neural networks (CNNs), can do everything a mathematical model can do without requiring you to be an expert on signal processing. Applied correctly, deep learning networks make signal processing tasks faster, more efficient, and more accurate.
