DSP in Loudspeakers
[feature] Loudspeaker systems are getting cleverer thanks to the incorporation of advanced digital signal processing algorithms that can compensate for some of the deficiencies in the transduction process. Various forms of nonlinear distortion may be reduced or it may be possible to get better performance out of smaller units by using electronics to counteract physical inadequacies. Some of these processes can make use of psychoacoustical phenomena, such as a means of extending the perceived bass response without actually reproducing the relevant low frequencies, and it may also be possible to modify the way in which the loudspeaker interacts with the listening room. Finally there are various ways by which it may be possible to engineer an all-digital signal chain, even using digital forms of representation right up to the point where the binary data is converted into an acoustical waveform.
