Reconstructing the song using its dominant frequencies

What are dominant frequencies?

Dominant frequency is defined as the highest magnitude sinusoidal component of the electrogram and is found by decomposing the electrograms into a finite number of sinusoidal constituents and finding the one with the highest magnitude.

What is dominant frequency in audio?

As alluded to earlier, the dominant frequency is the frequency of the sinusoidal waveform with highest amplitude. This sinusoidal waveform also is the one that best approximates the signal.
