Digital processors expanded studio production through programmable signal processing, automation and integrated digital control. Emerging in the late 1970s and developing rapidly through the 1980s and 1990s, dedicated digital hardware introduced new approaches to dynamics, filtering, pitch manipulation and complex audio processing.
This archive includes studio digital processors beyond dedicated reverb and delay units, covering multi-function systems and specialised digital signal processing hardware. These machines played a central role in the transition from analogue circuitry to software-based digital audio workflows.
