The main idea behind a peak limiter is that if we first reduce the peaks in the waveform, we have room to bring up the overall level of the sound without going over the digital ceiling This results in an overall louder average level. If an incoming or outgoing signal gets any louder, it will cause the waveform to “clip.” The result is a distorted sound and loss of information, as the system is not capable of mapping and storing the portion of the signal that went above full scale.
