The "standard" encoding for digital audio is pulse code modulation. The analog signal is sampled at regular intervals and stored as an amplitude quantity value.
- CD audio uses 44,100 amplitude samples per second
- Each sample is a 16-bit integer between -32,768 and 32,767
One way to synthesize a pure frequency (in Hz) is to sample a sine wave.
Your task is to implement a function from a number of milliseconds and a frequency to a collection of samples.
