The Period is #2Pi/B#, the Amplitude is the multiplier of the function. The midline is the vertical offset.

Explanation:

In this case, the period = #{2pi}/{{2pi}/3#= #{2pi}/1*3/{2pi}=3#

The amplitude is the leading scalar, 1/4

The vertical shift is zero, so the sound wave is centered on the x axis
