Matlab代写 - ECE2111 Assignment: Vuvuzela removal from broadcast audio
If you have watched the FIFA World Cup, chances are you have been tormented by the
incessant drone of the Vuvuzela. A Vuvuzela is a long plastic horn capable of producing a loud
monotone note that is very annoying and drowns out TV announcers. One way to reduce the
Vuvuzela noise and improve clarity of commentary in broadcasts is by using frequency-selecting
filtering that selectively suppresses particular frequency components generated by the Vuvuzela.
However, bear in mind that there may be some overlap between the frequency components of
the Vuvuzela and the frequency components in speech. This means that too much filtering may
attenuate the voices of commentators, which is undesirable.
