Born-Jordan quantization originates from the early quantum mechanics,
leading to sharp time-frequency localization of signals.
The related Born-Jordan transform provides
an attractive alternative to short-time Fourier transform.
We review the essential time-frequency analysis,
characterizing the Born-Jordan transform within Cohen's class,
and show how all this works in audio signal processing.
Computationally, our Born-Jordan approach is as complex as using spectrograms
(which suffer from arbitrariness of chosen analysis window,
resulting in inferior localization).
