What Is Crest Factor and Why Is It Important?

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.

Music: A typical Crest Factor is 18 to 20 dB. The significance of clipping events reported for arbitrary audio in Non-Referenced mode can be determined by assessing the Crest Factor of the original audio, and verifying the volume settings at the source to ensure sufficient headroom is provided to accommodate that ratio.

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 …
Crest Factor Measurement with AP2700 - Audio Precision

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 can set the inputs to GenMon. If we are measuring an external signal, we’ll need two identical signals or else a Y …

Headroom: How to Set Your Levels in Mixing and Mastering

As a quick reminder, crest factor is just the difference in decibels between the average and peak levels of a signal. Thus, if your average levels stay around that 0 mark on the K-20 meter, your peak levels might be anywhere between +10 and +15 and that would all be perfectly fine, because you’d still have at least 5 dB of headroom.
