Abstract
The broadcasting of audio contents by two loudspeakers is controlled by delivering a first audio content to the two loudspeakers and a further processing in which an auxiliary audio content is received. A second audio content is formed by temporally delaying the auxiliary audio content with a delay dependent on the spacing between the loudspeakers and on a distance between a first loudspeaker and a spot located in front of this first loudspeaker. The second audio content is delivered to the first loudspeaker. A third audio content is formed by inverting the auxiliary audio content. The third audio content is then delivered to the second loudspeaker.
Claims25
A method, comprising:
- receiving a first audio content,
- forming a second audio content by temporal delaying the first audio content with a delay dependent on a spacing between two loudspeakers and on a first distance between a first one of the two loudspeakers and a first spot located in front of this first loudspeaker,
- delivering the second audio content to the first loudspeaker,
- forming a third audio content comprising an inversion of the first audio content, and
- delivering the third audio content to a second one of the two loudspeakers.
Audio circuitry, comprising:
- a first input node adapted to receive first audio content;
- a first circuit adapted to formulate a second audio content by temporally delaying the first audio content with a delay dependent on a spacing between two loudspeakers and on a first distance between a first one of two loudspeakers and a first spot located in front of the first loudspeaker;
- a second circuit adapted to formulate a third audio content by inverting the first audio content;
- and
- delivery circuitry configured to deliver the second audio content to first loudspeaker and deliver the third audio content to a second one of the two loudspeakers.
