GNU Octave: Audio Data Processing
https://octave.org/doc/v4.0.0/Audio-Data-Processing.html
33.5 Audio Data Processing. Octave provides a few functions for dealing with audio data. An audio ‘sample’ is a single output value from an A/D converter, i.e., a small integer number (usually 8 or 16 bits), and audio data is just a series of such samples.

In this tutorial, we will use Octave V4.0.0 in Ubuntu and will start reading from audio files through writing and playing signals to emulate sounds used in a wide range of activities. Note that the main focus of this tutorial is not to install or learn to use an audio processing software already established, but rather to understand how it ...
Output Sound with Octave – Audio Processing With Octave

Output Sound with Octave. # We use ten values to generate one sin wave. We could also say, that we sample a 1Hz signal with 10Hz for one second and plot it. t= [0:0.1:1]; freq=1; plot (t, sin (t*2*pi*freq) # By increasing the value of the frequency e.g. to 2Hz,3Hz, or 4Hz we can easily recognize a higher frequnency.

The Matlab Signal Processing Toolbox provides the command spectrogram for computing and displaying a spectrogram (and Octave has the command stft). As a side effect, it returns the complex STFT data in a matrix. The myspectrogram function below illustrates computation of a spectrogram in matlab for purposes of basic spectrum analysis.

As we saw with audio representation, audio effects processing is typically done using either time- or frequency-domain algorithms that process a stream of audio vectors. An echo effect, for example, can be easily implemented by creating a buffer of sample memory to delay a sound and play it back later, mixing it in with the original.
