@Millercarbon:
First of all, wire is NOT “cast”; it’s drawn through a series of tungsten carbide or synthetic diamond dies, and annealed in a furnace under inert atmosphere every several passes to remove the work hardening from the drawing process.
Second, unless you are passing straight DC current; musical signals should be thought of as a mix of sign waves of many frequencies and amplitudes. Signal analyzers use a processing chip that does FFT (fast Fourier transformation) to reduce the musical signal to its component sign waves.
