The sounds library provides functions for constructing and playing sounds.
A wave is a function that takes in a number t and returns
a number representing the amplitude at time t.
The amplitude should fall within the range of [-1, 1].
A Sound is a pair(wave, duration) where duration is the length of the sound in seconds.
The constructor make_sound and accessors get_wave and get_duration are provided.
Sound Discipline:
For all sounds, the wave function applied to and time t beyond its duration returns 0, that is:
(get_wave(sound))(get_duration(sound) + x) === 0 for any x >= 0.
Two functions which combine Sounds, consecutively and simultaneously are given.
Additionally, we provide sound transformation functions adsr and phase_mod
which take in a Sound and return a Sound.
Finally, the provided play function takes in a Sound and plays it using your
computer's sound system.
