One of the surest ways to determine the real bitrate of an audio file is spectral (frequency) analysis. The option by ear will not be considered in this article. I must say right away that this method (like any other) is unlikely to give you the exact bitrate of the file, but getting a rough idea or a very approximate value of the complexity will not be difficult.

What is spectral analysis? (Definition) Spectrum analysis calculates the frequency of certain components of a signal, especially sound, these frequencies can be manipulated to hide data in an audio file. How to find a text in an audio file? Sometimes a text (some letters) or an image (rather a silhouette) is hidden in the sound spectrum.
