Vuvuzela filtering with parametric equalizers using System objects 1.0 Description
Description: This soccer season, denoising the noise from the vuvuzela has become very popular, as many fans find the noise from this instrument distracting from the game. In this example, we analyze the vuvuzela spectrum and identify its fundamental and first few harmonic frequencies. We then use parametric equalizers to selectively filter out these frequencies.
Notch parametric equalizers are used to remove the vuvuzela frequencies. As the notch filters may also remove components of the speech signal at the vuvuzela frequencies, a peak parametric equalizer is used to boost the speech signal at the output of the notch filters.
Stream processing techniques are used to process the input audio in "frames", and the filtering is done in a stream processing loop as well. Output audio is stored as a WAV file, and also logged to the MATLAB workspace, where the output results can be analyzed further.
This is an article which teaches the users how to develop an admin interface with the help of SQL-Server using system objects.

A component-based, object-oriented workflow system designed to allow workflows to be defined using XML or database records and implemented using PHP objects. New workflow actions may be developed and dropped into the system with no overhead.
The Simulink model in this submission implements a 3-band parametric equalizer using a time-varying IIR filter, whose filter coefficients are generated by a S-function. This S-function implements the digital parametric equalizer design algorithm...
This simple function generates polar stereographic maps of the Arctic and Antarctic with rectangular boundaries using Matlab's Mapping Toolbox. Typically, polar stereographic maps in Matlab appear with circular bounds, but this is often not the...
