On the Dither Performance of High-Order Digital Equalization for Loudspeaker Systems

Experimental results derived using real-time hardware together with supporting software simulations reveal that for infinite impulse response digital filters low-level chaos acts as self-dither, which both decorrelates truncation distortion and aids linearization of low-level digital-to-analog conversion nonlinearity. The process is examined for a range of filter responses, in particular those that can match the requirements for loudspeaker equalization.
