Although .wav is widely used when audio data analysis is concerned. Once you have successfully installed and imported libROSA in your jupyter notebook. You can read a given audio file by simply passing the file_path to librosa.load() function. librosa.load() —> function returns two things — 1. An array of amplitudes. 2. Sampling rate.

Audio Data Analysis using Python. Before we discuss audio data analysis, it is important to learn some physics-based concepts of audio and sound, like its definition, and parameters such as amplitude, wavelength, frequency, time-period, phase intensity, etc. Here are some concepts and mathematical equations. Sound is a form of energy that is ...
audio - Window size vs data length for FFT - Stack Overflow
https://stackoverflow.com/questions/5570355/window-size-vs-data-length-for-fft
I am trying to do a quick spectral analysis on the streaming audio data to capture vowels (something like JLip-sync). Using PyAudio to capture the voice data in small chunks (1024) for short durations (0.0625 sec.). Using numpy.fft for the analysis, and to get rid of leakage using numpy.hanning window.

https://training.dewesoft.com/online/course/fft-spectral-analysis
This analysis can be expressed as a Fourier series. Fourier series. Any periodic waveform can be decomposed into a series of sine and cosine waves: where a0, an, and bn are Fourier coefficients:,, Discrete Fourier transform. For discrete data, the computational basis of spectral analysis is the discrete Fourier transform (DFT).
