Method for determining a processed audio signal and a handheld device

摘要

A method for determining a processed audio signal, comprising: establishing an ad-hoc network between a plurality of handheld devices, each handheld device having a microphone; picking up a plurality of audio signals with each microphone of the plurality of handheld devices; distributing the plurality of audio signals within the ad-hoc network such that in at least one handheld device at least two of the plurality of audio signals are available; combining, in said at least one handheld device, the at least two of the plurality of audio signals to obtain said processed audio signal.

1. A method for determining a processed audio signal, the method comprising:
establishing an ad-hoc network between a plurality of handheld devices, each handheld device including a microphone; determining position information for each of the plurality of handheld devices; displaying on a display a location of each of the plurality of handheld devices based on the position information of each of the plurality of handheld devices; picking up a plurality of audio signals with each microphone of the plurality of handheld devices; displaying on the display a location of at least one source of the plurality of audio signals; selecting a target location from the displayed location of the at least one source; distributing the plurality of audio signals within the ad-hoc network such that at least two audio signals of the plurality of audio signals are available in at least one handheld device; and combining, in said at least one handheld device, the at least two of the plurality of audio signals by:
beamforming the at least two of the plurality of audio signals to focus on the target location;aligning the at least two of the plurality of audio signals to a common reference point based on the position information of the plurality of handheld devices; andadding the at least two of the plurality of audio signals to obtain said processed audio signal.
