Abstract
An apparatus receives a first audio signal captured by a first microphone of a device and at least a second audio signal captured by at least a second microphone of the device. The apparatus estimates a diffuseness of sound based on the received first and at least second audio signals. The apparatus may then form at least one final audio signal based on at least one of the received first audio signal and the received at least second audio signal by adjusting an audibility of diffuse sound for the final audio signal in response to the estimated diffuseness, in order to enable an enhanced perception of sound with respect to at least one criterion with the at least one final audio signal.
Claims20
A method comprising:
- receiving, by an apparatus, a first audio signal captured by a first microphone of a device and at least a second audio signal captured by at least a second microphone of the device;
- estimating, by the apparatus, a diffuseness of sound based on the received at first and at least second audio signals;
- and
- forming, by the apparatus, at least one final audio signal based on at least one of the received first audio signal and the received at least second audio signal by adjusting an audibility of diffuse sound for the final audio signal in response to the estimated diffuseness, in order to enable an enhanced perception of sound with respect to at least one criterion with the at least one final audio signal.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory coupled to the at least one processor, and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
- receive a first audio signal captured by a first microphone of a device and at least a second audio signal captured by at least a second microphone of the device;
- estimate a diffuseness of sound based on the received first and at least second audio signals;
- and
- form at least one final audio signal based on at least one of the received first audio signal and the received at least second audio signal by adjusting an audibility of diffuse sound for the final audio signal in response to the estimated diffuseness, in order to enable an enhanced perception of sound with respect to at least one criterion with the at least one final audio signal.
