On the design of high order digital audio equalizers
2007 International Symposium on Intelligent Signal Processing and Communication Systems, 2007This paper presents a new approach for designing high order digital audio equalizer filters. The new design is based on odd order analog allpass filters and bilinear transformation. The analog allpass filters are designed using Butterworth, Chebyshev I, Chebyshev II and elliptic polynomials.

Equalization of a PC Audio Card
2005The main goal of this paper was the equalization of an inexpensive PC audio card and the application of a PC computer as a storage device for the sound pressure and vibration measurements. Since magnitude response of the audio card is not flat in the desired frequency band, a finite impulse response (FIR) digital filter was designed and implemented in ...

Digital data equalizing in multitrack digital audio recording
ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005Digital Audio stationary-head recording is performed with recording densities requiring playback equalization to reduce intersymbol interference. In today's digital audio recorders, data retrieval is usually implemented with analog circuits (equalizing filters, DC component restoration, data detectors) with manual adjustment.

IIR filter approximation of an innovative digital audio equalizer
2013 8th International Symposium on Image and Signal Processing and Analysis (ISPA), 2013Digital audio equalization is used to enhance the listening experience introducing corrections in the auditory frequency response. The equalizer performance depends on its implementation which includes optimal filters with sharp transition bandwidth development and a low computational complexity.

An audio graphic equalizer IC with monolithic filter technique
International Conference on Consumer Electronics, 1989An audio graphic equalizer IC has been developed using a monolithic filter technique. This technique has made it possible to realize a perfectly on-chip graphic equalizer without external components, and offers a DC control structure. >

Evaluation and alternative regularization of audio equalization techniques
2013Inverse-filtering techniques are used in audio equalization of rooms and loudspeakers to correct or enhance the listening environment and to create virtual reality audio systems. The inverse-filtering concept is based on the concept that one can undo a system (loudspeaker, room, or some audio/acoustic path) completely or modify it to some desired ...
