Document Summary

To mix sound waves, it helps to understand the cycle of vibration for each and how everything is illustrated on a waveform. Using a waveform, we can obtain information about the frequency of vibration, the amplitude of vibration, and the phase characteristics. The frequency of the vibration can be determined from the waveform by determining the period of the cycle. The cycle information can also give us information about wavelength. Wavelength is the distance covered by during one cycle of vibration. Two characteristics of the vibration determine the wavelength, the frequency (f) and the velocity (c) of the sound wave. The formula for determining wavelength is: wavelength = velocity/frequency. Obviously, things that have shorter cycles are not going to travel as far in one cycle as things that have longer cycles. Thus, because high frequency sounds have shorter cycles, they have shorter wavelengths.
