Self-Adjusting Audio Equalizer, A

2014
One goal of an audio equalizer is to adjust an audio signal to compensate for the acoustics of the speakers playing the signal as well as the room in which the signal is played. Certain frequency bands are amplified while others are attenuated, so that any damping of the sound in the room is 'equalized' and, ideally, the frequency response of the audio

An Efficient Multichannel Equalization Algorithm for Audio Applications

2007 IEEE International Conference on Acoustics, Speech and Signal Processing - ICASSP '07, 2007
The challenge of multichannel equalization for audio applications lies in the physical properties of the underlying multi-input/multi-output (MIMO) linear time-invariant systems which are generally non-minimum phase and exhibit extremely long impulse responses, thereby imposing a considerable computational burden on the equalization task particularly ...

Equalizer and audio device using the same

The Journal of the Acoustical Society of America, 1997
An equalizer includes: a first attenuating circuit which receives an input signal and a first control signal and attenuates the input signal depending on the level of the first control signal; a filter having a predetermined frequency band which receives the output from the first attenuating circuit; an adding circuit which receives the output from the

An Automatic Graphic Equalizer for Car Audio Systems

SAE Technical Paper Series, 1984
<div class="htmlview paragraph">Although a graphic equalizer is almost essential for high quality automobile audio systems, consumers, not knowing the actual data of the field in automotive cabins, often have difficulty making a satisfactory adjustment.

Method and equalization of home audio systems

The Journal of the Acoustical Society of America, 1982
A method is provided for correcting errors in the overall reproduction characteristics of an audio system installed in a residence. The method may include the steps of generating a test signal as an input to the audio system and converting the resulting sound generated by the system and its room environment into stored data whose values are a function ...

Optimum digital audio equalizers with flat frequency response

2012 9th International Conference on Communications (COMM), 2012
In this paper a design method of the optimum digital audio equalizers with small ringing impulse responses, by using symmetric B-spline functions is presented. It is important to have a flat frequency response for the audio equalizer. The solution is to approximate the response of each frequency band by using spline functions, that insures continuous ...

Optimal Design of Digital Audio Parametric Equalizer

Journal of Information and Computational Science, 2014
The traditional design method of digital audio parametric equalizer often has spectrum aliasing between two adjacent sub-filters with closed center frequencies. A modified design method for digital parametric equalizer is proposed in this paper. A computer-aided design method is adopted to approach the desired amplitude-frequency responses based on ...

Parametric Hear through Equalization for Augmented Reality Audio

ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019
Augmented Reality (AR) audio applications require headphones to be acoustically transparent so that real sounds can pass through unaltered for natural fusion with virtual sounds. In this paper, we consider a multiple source scenario for hear through (HT) equalization (EQ) using closed-back circumaural headsets.

Comparative Analysis of Audio Equalizer Typologies

This paper analyzes three distinct topologies of audio equalizers. The focus is on understanding the fundamental principles behind each topology the Three-band equalizer, the five-band equalizer, and the single input multi-band split topology by examining their block diagrams, schematics, and working principles.
