Abstract
Official abstract text for this publication.
An audio processing system includes an audio processing device and an external device, the audio processing device having a signal processing unit adapted for running an algorithm for processing an input signal representing an acoustic signal from the environment of the user and providing a processed output signal. The external device includes in an information signal a measure, characteristic of the reverberation of the room or location where the audio processing device is located, and the audio processing device is adapted to extract the measure of the reverberation from the information signal and use the measure as an input to an algorithm that includes a directional algorithm for providing a directional characteristic of the input signal.
First claim
Opening claim text (preview).
The invention claimed is: 1. An audio processing system comprising: an audio processing device and an external device physically detached from the audio processing device and wirelessly transmitting to the audio processing device information about characteristics of a room or location, where the audio processing device is located, said audio processing device including an input transducer providing an electric input signal representing an acoustic signal from an environment of a…
