Loudspeaker Equalization with Post-Processing
Loudspeaker equalization is an essential technique in audio system design. A well-known equalization scheme is based on the deconvolution of the desired equalized response with the measured impulse response of the loudspeaker. In this paper, a postprocessing scheme is combined with the deconvolution-based algorithm to provide a better equalization effect. Computer simulation results are given t...
متن کاملCombined quasi-anechoic and in-room equalization of loudspeaker responses
This paper presents a combined approach to loudspeaker/room response equalization based on simple inroom measurements. In the first step, the anechoic response of the loudspeaker, which mostly determines localization and timbre perception, is equalized with a low-order non-minimum-phase equalizer. This is actually done using the gated in-room response, which means that the equalization is incor...
متن کاملFull room equalization at low frequencies with asymmetric loudspeaker arrangements
For rectangular rooms with symmetric loudspeaker arrangements, full room equalization can be achieved at low frequencies, as demonstrated by previous research. The method is based on generating a plane wave that propagates along the room. However, often the room is not rectangular, and/or a symmetric loudspeaker setup cannot be assured, leading to a deteriorated equalization performance. In add...
متن کاملModal Equalization of Loudspeaker–Room Responses at Low Frequencies*
A loudspeaker installed in a room acts as a coupled system where the room properties typically dominate the rate of energy decay. At high frequencies, typically above a few hundred hertz, passive methods of controlling the rate and properties of this energy decay are straightforward and well established. Individual strong reflections are broken up by diffusing elements in the room or trapped in...
متن کاملOn 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 ...
