In part 2 of this article series, we will explore how filters — that invariably change level or phase as a function of frequency — can affect crest factor. Towards the end, you can download a MS Excel Workbook for free that contains all relevant calculations and graphics used in this article.

Crest factor is an important metric associated with phenomena such as (but not limited to) headroom, distortion, instantaneous power consumption, and loudspeaker driver excursion.

In part 1 of this 4‑episode series on crest factor, we will begin by defining crest factor first. Towards the end, you can download a MS Excel Workbook for free that contains all relevant calculations and graphics used in this article.

Subsequent episodes will cover crest factor and filters, crest factor and power consumption, and crest factor in the air: measuring sound levels.

White and Red Pulse in AudacityFigure 1A short story about my favorite audio signal (at the time of writing) for auditioning time smearing in sound systems.

Randomizing Sample OrderFigure 1What happens when you randomize the sample order of pink noise? Let's start with white noise first.

It is extremely gratifying to have accurate 3D prediction software confirm and validate tried and tested loudspeaker selection, positioning, and aiming techniques, some of which predate prediction software all together.

Industry legend Bob "6o6" McCarthy created simple but reliable methods such as Forward Aspect Ratio and Lateral Aspect Ratio which minimize variance over listening‑space, that empower audio professionals to deploy loudspeakers without computer aid.
