Crest factor, defined Simply stated, crest factor—sometimes called peak-to-average ratio—is the difference in decibels between the peak and average levels of a signal. In the strictest technical sense, it only applies to steady-state signals like sine, square, saw, or triangle waves. In that context, a crest factor measurement might look like this:

The crest factor of an audio signal is the dB difference between the peaks and the RMS value of the signal. The RMS (Root Mean Square) is defined as the “heating value” of the signal – the voltage that would generate the same heat as a DC (Direct Current) signal, over the same time. The RMS value of a complex signal must be read with an RMS voltmeter.

Typically music has a crest factor of 10 to 20 dB (much more in some cases). That loosely means there is a 10 to 20 dB difference between the peak and the “average” electrical power of the music. Now, think about what a compressor does: it decreases the dynamic range of an audio signal, usually by lowering the peaks.

The crest factor is the ratio between peak level and RMS level of a wave form. It can be specified as voltage ratio or dB ratio. A high peak level compared to a low RMS level is caused for instance by sharp peaks in the waveform that don't contain much energy. These peaks do not last for a …

Answer: Crest factor is the difference between the Peak and RMS values of a signal. To measure it, we will need to put the same signal into both Channel A and Channel B analyzer inputs. If we are measuring an internally generated signal, we …

Crest factor reduction is a digital processing function which can reduce the PAR of a signal. A simple way to accomplish this is to simply limit or saturate the peaks in the digital signal amplitude. The problem with this is that it produces high-frequency spectrum components which will cause interference in the adjacent frequency spectrum.
