Digital audio fundamentals
This composite waveform still doesn't account for the uniqueness of the sound of different
instruments. For example, stringed instruments usually have a resonator. In the case of the guitar,
the resonator is the big block of hollow wood to which the string is attached (the guitar body). This
has a major impact on the sound we perceive when a guitar is played because it enhances or
amplifies some of the vibrations produced by the string and diminishes or attenuates others. The
ultimate effect of all the vibrations occurring simultaneously, being altered by the resonator, adds up
to the sound we know as guitar.
