Abstract
Various example embodiments relate to microphone signal processing. For example, a method is disclosed comprising enabling acoustic echo cancellation, AEC, processing on at least one captured microphone signal in response to a trigger event, wherein the AEC processing is performed for a first time period for providing at least one post-processed captured microphone signal. The method may also comprise applying ambient noise suppression processing on the at least one post-processed captured microphone signal, wherein a level of ambient noise suppression applied on the at least one post-processed captured microphone signal is increased from a first level to one or more second levels in response to AEC processing being enabled.
Claims20
An apparatus comprising:
- at least one processor;
- at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- enable acoustic echo cancellation, AEC, processing on at least one captured microphone signal in response to a trigger event, wherein the AEC processing is performed for a first time period for providing at least one post-processed captured microphone signal;
- and
- apply ambient noise suppression processing on the at least one post-processed captured microphone signal, wherein a level of ambient noise suppression applied on the at least one post-processed captured microphone signal is increased from a first level to one or more second levels in response to the AEC processing being enabled.
A method, comprising:
- enabling acoustic echo cancellation, AEC, processing on at least one captured microphone signal in response to a trigger event, wherein the AEC processing is performed for a first time period for providing at least one post-processed captured microphone signal;
- and
- applying ambient noise suppression processing on the at least one post-processed captured microphone signal, wherein a level of ambient noise suppression applied on the at least one post-processed captured microphone signal is increased from a first level to one or more second levels in response to the AEC processing being enabled.
A non-transitory computer readable medium comprising instructions, when executed by an apparatus, cause the apparatus to perform at least the following:
- enabling acoustic echo cancellation, AEC, processing on at least one captured microphone signal in response to a trigger event, wherein the AEC processing is performed for a first time period for providing at least one post-processed captured microphone signal;
- and
- applying ambient noise suppression processing on the at least one post-processed captured microphone signal, wherein a level of ambient noise suppression applied on the at least one post-processed captured microphone signal is increased from a first level to one or more second levels in response to the AEC processing being enabled.
