Researchers develop technique for better wireless audio

The Eindhoven-based Holst Centre and the Leuven-based imec have a chip will be developed which is better suited for the wireless sending and receiving audio over the bluetooth or other standards. The technique is called Impulse Ultra-wideband.

With the new chip promising the researchers that audio can more efficiently be transmitted and received, with a higher quality. The technique would be more suitable for, for example, wireless headphones than bluetooth. That would be possible because Uwb signals have very low power across a wide frequency spectrum broadcasts. The technique can therefore only be used for small distances, up to twenty meters, but requires a lot less energy.

The combination of low intensity and a broad spectrum has as side effect that the signal has no interference for other signals. That is because the signal is broadcast on frequencies where other signals their noise emitting. Uwb has existed for longer; it went to the researchers about the signals to be distinguished from the noise of other sources. This could also be the long development time of the technology explain.

According to the researchers, the chip can also be used for the location or positioning to do. To achieve this calls for the research companies to help.
