Speeding Learning of Personalized Audio Equalization
2014 13th International Conference on Machine Learning and Applications, 2014Audio equalizers (EQs) are perhaps the most commonly used tools used in audio production. The SocialEQ project is a web-based personalized audio equalization system that uses an alternative interface paradigm to the standard approach. Here, the user names a desired effect (e.g. Make the sound "warm") and teaches the tool (e.g.

A New Approach to Digital Audio Equalization
2007 IEEE Workshop on Applications of Signal Processing to Audio and Acoustics, 2007The design and implementation of a M-band linear phase digital audio equalizer system is presented. Beginning from analysis/synthesis filterbank, an innovative uniform and non uniform bands audio equalizer is derived using multirate properties. In literature fixed frequency response equalization has well-known problems due to algorithms implementation.

Self-correcting audio equalizer
The Journal of the Acoustical Society of America, 1983A self-correcting audio equalizer is disclosed for use in a high fidelity sound reproduction system. The equalizer (46) responds to the audio signal to provide an equalized audio signal to a sound reproducing device (28) for generating a corresponding acoustic signal.

Current audio equalization techniques include Shelf, Parametric, and Graphic Equalizers. They are prevalent in all professional and commercial audio implementations. These techniques modify spectral components within specified bands by applying gain or attenuation. However, current techniques each have inherent issues with their use.

Design and synthesis of the audio equalizers
Proceedings 7th International Conference on Signal Processing, 2004. Proceedings. ICSP '04. 2004., 2005This paper designs and synthesizes audio equalizers for multimedia applications. In order to prevent the equalizers from boosting undesired frequency components, the peaks of the inverse model of room transfer function are clipped. Different techniques are then used to synthesize the equalizer from the clipped amplitude response.

Multi-rate sampling digital audio equalizer
IEEE Proceedings of the SOUTHEASTCON '91, 2002The advantages of implementing a digital audio equalizer using multirate sampling techniques vs. fixed sampling are presented. A theoretical discussion of multirate sampling equalization design issues such as processor computational bandwidth, number of equalizer bands, frequency resolution in a particular band, and filter type and order are reviewed ...

Cable equalizer for aes digital audio data
The Journal of the Acoustical Society of America, 2002An electrical signal is equalized at the receiving end of a transmission path by applying the signal both to a frequency-dependent emphasizer and to a first port of a mixer and applying the output signal of the frequency-dependent emphasizer to a second port of the mixer.
