COCKTAIL-PARTY-PROCESSOR

A Cocktail-Party-Processor, which is able to suppress sound from directions, which are different to the direction of a desired sound source, can also be used to reduce the effect of echoes and reverberation. Since all those "mirror sound sources" are suppressed, whose directions do not match to the direction of desired sound source, the total number of perceived mirror sound sources is reduced. As a result, the perceived sound will contain less echoe and reverberation... Sound of a specific direction leads to characteristical interaural time and level differences between both ear signals. If the direction of a desired sound source is known, their interaural time and level differences can be used to extract a desired sound source: Signal portions, where interaural time and level differences fit to the desired direction, are accepted, Signal portions, where interaural time and level differences do not fit to the desired direction, are suppressed,...
