New software may help banish feedback at rock concerts

London, April 3 : That irritating "feedback" noise during rock concerts may soon become a thing of past, for a research team has designed an automated system to prevent its occurrence.

The new system is based on software written by researchers at the University of London, which automatically lowers frequencies that give rise to feedback sounds.

Feedback is basically a squealing noise springing from escalating frequencies, which are generated when the microphones recapture and resend a frequency to the speakers.

Generally, the sound engineer lowers the volumes of frequencies to prevent feedback during a performance, but this is a time-consuming process.

Joshua Reiss of the Centre for Digital Music at the Queen Mary University of London insists that the new software will help free the sound engineer to focus his entire focus on music quality, rather than prevent feedback.

The researcher has revealed that the software lowers a frequency slightly when it rises above its critical volume, reports the Scotsman.

Reiss adds that the software also lowers the other frequencies to keep the balance of sounds.
