Abstract

An audio device comprising an interface, a memory, and one or more processors is disclosed, wherein the one or more processors are configured to: obtain a microphone input signal; obtain a media input signal; process the microphone input signal for provision of a microphone output signal; and provide an audio output signal based on the microphone output signal, wherein to process the microphone input signal comprises to: determine a microphone gain; and apply the microphone gain to the microphone input signal for provision of the microphone output signal, and wherein to determine the microphone gain comprises: estimate a first loudness of the microphone input signal; determine a first primary average based on the first loudness; estimate a second loudness of the media input signal; determine a second average based on the second loudness; determine a first gain based on the first primary average and the second average; determine a first secondary average based on the first loudness; determine a second gain based on the first secondary average and the second average; and determine the microphone gain based on the first gain and the second gain.

Claims (31)

1 . An audio device comprising an interface, a memory, and one or more processors, wherein the one or more processors are configured to:

obtain a microphone input signal;

obtain a media input signal;

process the microphone input signal for provision of a microphone output signal; and

provide an audio output signal based on the microphone output signal,

wherein to process the microphone input signal comprises to:

determine a microphone gain; and

apply the microphone gain to the microphone input signal for provision of the microphone output signal, and

wherein to determine the microphone gain comprises:

estimate a first loudness of the microphone input signal;

determine a first primary average based on the first loudness;

estimate a second loudness of the media input signal;

determine a second average based on the second loudness;

determine a first gain based on the first primary average and the second average;

determine a first secondary average based on the first loudness;

determine a second gain based on the first secondary average and the second average; and

determine the microphone gain based on the first gain and the second gain.

2 . The audio device according to claim 1 , wherein to determine a first primary average comprises to determine the first primary average over a first primary time period, and wherein to determine the first secondary average comprises to determine the first secondary average over a first secondary time period smaller than the first primary time period.

3 . The audio device according to claim 1 , wherein to determine a second average comprises to determine the second average over a second time period.

4 . The audio according to claim 1 , wherein to determine a first gain comprises to determine the first gain based on the first primary average, the second average, and a current first gain.

5 . The audio according to claim 1 , wherein to determine the microphone gain comprises to determine a noise gain, and to determine the microphone gain comprises to determine the microphone gain based on the noise gain.

6 . The audio according to claim 5 , wherein to determine the noise gain comprises to determine a first noise average, and determine the noise gain based on the first noise average.

7 . The audio according to claim 5 , wherein to determine the noise gain comprises to determine a second noise average, and determine the noise gain based on the second noise average.

8 . The audio device according to claim 1 , the audio device comprising a first voice activity detector, wherein to process the microphone input signal comprises to determine, using the first voice activity detector, whether the microphone input signal comprises a user voice for provision of first voice detector output indicative of presence of user voice, and wherein to determine the first primary average and/or to determine the first secondary average is paused when user voice is present.

9 . The audio device according to claim 5 , wherein to determine the noise gain comprises to determine a first noise average, and determine the noise gain based on the first noise average, the audio device comprising a first voice activity detector, wherein to process the microphone input signal comprises to determine, using the first voice activity detector, whether the microphone input signal comprises a user voice for provision of first voice detector output indicative of presence of user voice, and wherein to determine the first primary average and/or to determine the first secondary average is paused when user voice is present, and wherein to determine the first noise average and/or to determine the second noise average is paused when user voice is present.

10 . The audio device according to claim 1 , wherein to determine the microphone gain comprises to determine a voice activity gain, and to determine the microphone gain comprises to determine the microphone gain based on voice activity gain.

11 . The audio device according to claim 10 , the audio device comprising a second voice activity detector, wherein to process the microphone input signal comprises to determine, using the second voice activity detector, whether the microphone input signal comprises a far field voice for provision of second voice detector output indicative of presence of far field voice, and wherein to determine the voice activity gain is based on the second voice detector output.

12 . The audio device according to claim 1 , wherein to estimate a first loudness of the microphone input signal comprises to estimate a first power of the microphone input signal, and determine the first loudness based on the first power.

13 . The audio device according to claim 1 , wherein to estimate a second loudness of the media input signal comprises to estimate a second power of the media input signal, and determine the second loudness based on the second power.

14 . The audio device according to claim 1 , wherein to determine the second gain comprises to determine the second gain based on the first gain.

15 . The audio device according to claim 1 , wherein to provide the audio output signal comprises to mix the microphone output signal and the media input signal.
