Selective AEC filter bypass
View Patent ↗An apparatus for selective AEC filter bypass is disclosed. A method and computer program product also perform the functions of the apparatus. An apparatus for selective AEC filter bypass is disclosed that includes a filter for an audio handling device that performs acoustic echo cancellation (AEC) on a microphone signal to produce an AEC-filtered microphone signal, a bypass controller that determines whether an AEC bypass parameter corresponding to an audio stream is enabled and a mixer that combines the audio stream with the AEC-filtered microphone signal to produce an AEC-filtered selectively combined signal in response to determining that the AEC bypass parameter corresponding to the audio stream is enabled.
1. An apparatus comprising:
a filter for an audio handling device that performs acoustic echo cancellation (AEC) on a microphone signal to produce an AEC-filtered microphone signal;
a bypass controller that determines whether an AEC bypass parameter corresponding to an audio stream is enabled; and
a mixer that combines the audio stream with the AEC-filtered microphone signal to produce an AEC-filtered selectively combined signal in response to determining that the AEC bypass parameter corresponding to the audio stream is enabled.
2. The apparatus of claim 1 , wherein the bypass controller automatically enables the AEC bypass parameter in response to detecting a start of the audio stream during an ongoing bidirectional communication session over a network.
3. The apparatus of claim 1 , wherein the bypass controller enables the AEC bypass parameter based on one or more of a type of the audio stream and an AEC setting for the audio stream.
4. The apparatus of claim 3 , further comprising a user interface for selecting the AEC setting for the audio stream.
5. The apparatus of claim 4 , wherein the user interface for selecting the AEC setting for the audio stream is displayed in response to detecting a start of the audio stream during an ongoing bidirectional communication session of voice data over a network.
6. The apparatus of claim 5 , wherein the AEC setting is initialized at the start of the bidirectional communication session to disable the AEC bypass parameter for the audio stream.
7. The apparatus of claim 5 , wherein the AEC setting is initialized at the start of the bidirectional communication session to enable the AEC bypass parameter for the audio stream.
8. The apparatus of claim 2 , wherein the audio stream comprises one or more individual audio streams to be combined with the AEC-filtered microphone signal.
9. The apparatus of claim 8 , wherein the AEC setting for the audio stream comprises one or more individual settings corresponding respectively to the one or more individual audio streams.
10. The apparatus of claim 1 , wherein the audio handling device is a near end portable computing device and the AEC-filtered selectively combined signal is communicated at least over a wireless connection to a far end device.
11. A method comprising:
performing acoustic echo cancellation (AEC) on a microphone signal to produce an AEC-filtered microphone signal;
determining whether an AEC bypass parameter corresponding to an audio stream is enabled; and
combining the audio stream with the AEC-filtered microphone signal to produce an AEC-filtered selectively combined signal in response to determining that the AEC bypass parameter corresponding to the audio stream is enabled.
12. The method of claim 11 , further comprising automatically enabling the AEC bypass parameter in response to detecting a start of the audio stream during an ongoing bidirectional communication session of voice data over a network.
13. The method of claim 11 , wherein enabling the AEC bypass parameter is based on one or more of a type of the audio stream and an AEC setting for the audio stream.
14. The method of claim 13 , further comprising selecting the AEC setting for the audio stream.
15. The method of claim 14 , further comprising displaying a user interface for selecting the AEC setting for the audio stream in response to detecting a start of the audio stream during an ongoing bidirectional communication session of voice data over a network.
16. The method of claim 15 , wherein the AEC setting is initialized at the start of the bidirectional communication session to disable the AEC bypass parameter for the audio stream.
17. The method of claim 15 , wherein the AEC setting is initialized at the start of the bidirectional communication session to enable the AEC bypass parameter for the audio stream.
18. The method of claim 12 , wherein the audio stream comprises one or more individual audio streams to be combined with the AEC-filtered microphone signal.
19. The method of claim 18 , wherein the AEC setting for the audio stream comprises one or more individual settings corresponding respectively to the one or more individual audio streams.
20. A system comprising:
an audio handling device comprising one or more processors, computer readable storage media, and code executable by the one or more processors;
one or more microphones that provide a microphone signal to the audio handling device;
one or more speakers that play audio output from the audio handling device, wherein the audio handling device is configured to:
perform acoustic echo cancellation (AEC) on the microphone signal to produce an AEC-filtered microphone signal;
determine whether an AEC bypass parameter corresponding to an audio stream is enabled; and
combine the audio stream with the AEC-filtered microphone signal to produce an AEC-filtered selectively combined signal in response to determining that the AEC bypass parameter corresponding to the audio stream is enabled.
