DSP

Sources use the term to describe the digital engine inside effects such as delays, reverbs, compressors, octavers, and distortions, whether emulating analog or vintage designs or creating original sounds¹²³⁴. Some pedals use DSP to recreate the character of older technology, such as a DSP chip emulating a BBD analog effect or a DSP unit recreating magnetic memory drums³⁴. Others pursue high sound quality directly, such as a 32-bit high-precision DSP used without simulation or modeling⁵. The term also appears in product names and rig descriptions, such as DSP guitar rigs using amp and IR pedals, and powerful DSP enabling modeling with responsiveness to playing dynamics⁶⁷.
