Modeling and Delay-Equalizing Loudspeaker Responses

Nonlinear Modeling of a Guitar Loudspeaker Cabinet

Distortion is a desirable effect for sound coloration in electric guitar amplifiers and effect processors. At high sound levels, particularly at low frequencies, the loudspeakers used in classic style cabinets are also a source of distortion. This paper presents a case study of measurements and digital modeling of a typical guitar loudspeaker as a real-time audio effect. It demonstrates the com...

Combined 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...

Modal 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...

Inverse filtering of a loudspeaker and room acoustics using time-delay neural networks

This paper presents the design of a neural-based acoustic control used for the equalization of the response of a sound reproduction system. The system usually can be modeled as a composite system of a loudspeaker and an acoustic signal-transmission channel. Generally, an acoustic signal radiated inside a room is linearly distorted by wall reflections. However, in a loudspeaker, the nonlinearity...
