Unison

Broadband noise is a strain of noise music that centers on wide-spectrum, non-tonal sound masses that occupy most or all of the audible frequency range. Instead of melody or rhythm, it foregrounds texture, spectral density, and perceived loudness. Artists generate full-band energy using white/pink/brown noise sources, mixer and amplifier feedback, radio static, and heavily saturated effects chains. The aesthetic goal is continuous, immersive sonic pressure in which discrete events are masked by a dense, evolving field of sound. While it intersects with harsh noise, broadband noise is defined by its broad spectral spread and saturating presence, prioritizing timbral contour, dynamics, and textural change over structure in the traditional musical sense.
