METHOD AND SYSTEM FOR OBTAINING AN AUDIO SIGNAL
First Claim
1. A method comprising:
- receiving a first sound signal at a first microphone arranged at a first height vertically above a substantially flat surface;
receiving a second sound signal at a second microphone arranged at a second height vertically above the substantially flat surface;
processing a signal provided by the first microphone using a low pass filter;
processing a signal provided by the second microphone using a high pass filter;
adding the signals processed by the low pass filter and the high pass filter to form a sum signal; and
outputting the sum signal as an audio signal.

11. A system comprising:
-
a first microphone, which receives a first sound signal, arranged at a first height vertically above a substantially flat surface; a second microphone, which receives a second sound signal, arranged at a second height vertically above the substantially flat surface; a low pass filter configured to process a signal provided by the first microphone; a high pass filter configured to process a signal provided by the second microphone; and an adder configured to add an output signal provided by the low pass filter and an output signal provided by the high pass filter to form a sum signal output as an audio signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
