PD18: Can DSP fix a bad speaker?
Adaptive nonlinear loudspeaker control algorithms implemented in low-cost DSP’s allows speakers to be driven very close to their physical limits, producing the maximum SPL and increasing the reliability. While distortion caused by deterministic motor and suspension nonlinearities can be cancelled by digital signal processing, residual distortion commonly known as “Rub&Buzz” becomes more audible and has to be fixed by the transducer manufacturer or system integrator as it can never be compensated by electrical means. This tutorial focusses on particularities, design goals and requirements of optimal passive systems for adaptive nonlinear control. Measurement methods that combine perceptual and physical metrics are introduced to provide a comprehensive evaluation of the transducer, enclosure and amplifier intended for adaptive nonlinear control.
