Practical Techniques for Sinusoidal Approximation in Audio
Sinusoids are the raw materials of sound. When we understand the composition and properties of sinusoids we fundamentally enhance our ability to work with sound. Working with sinusoidal signals and building intuition for their mathematical approximations can increase confidence when facing more complex signal-processing tasks. This talk is for anyone curious about how and why we approximate sinusoidal signals, how we measure the accuracy and efficiency of those approximations and how we identify the cases where custom approximations are worthwhile.
