WebSep 12, 2024 · Sine has a period of \(2 \pi\), meaning that it repeats its output after multitudes of \(2 \pi\). As we want to create a sine wave which repeats 440 times a second \(\left( 440~\text{Hz} = 440 \frac{1}{\text{sec}} \right)\) we need to take account the periodicity of sine as we need to scale it to our ticking clock, the samplerate.,We can now … human and animal instincts
