Linear sound wave
Nettet12. sep. 2024 · Recall that the linear wave equation is (16.4.5) ∂ 2 y ( x, t) ∂ x 2 = 1 v 2 ∂ 2 y ( x, t) ∂ t 2. Therefore, (16.4.6) 1 v 2 = μ F T. Solving for v, we see that the speed of … NettetSound waves consist of fluctuations of pressure in the air. Usually, the fluctuation is a very small fraction of the ambient atmospheric pressure, and that means that, as with small-amplitude mechanical vibrations, most relevant aspects of musical sound can be understood using linear theory.

These triangular filters are applied to the STFT to extract the power spectrum.
