An apparatus including at least one processor and at least one memory including computer program code configured to: when the apparatus is in a voice phone call mode of sound capture, output a signal from a first microphone as a primary speech signal, and select one or more second microphones to output a noise reduction signal, where the apparatus comprises at least two of the second microphones, and where selection of the one or more second microphones is based at least partially upon a determined use of the apparatus being either a handportable or an integrated handsfree use; and/or when the apparatus is in a multi-media mode of sound capture select one or more of the microphones to output audio signals based upon both a determined type of sound capture feature being used by the apparatus and based upon a determined orientation of the apparatus.

Audio capture with multiple microphones

An audio processing scheme is described. In an example, an apparatus comprises: at least two acoustic sensors through which audio content is received; at least one other sensor; an audio processor connected to the sensors and configured to receive audio information from the acoustic sensors and other information from the other sensor. The audio processor is configured to determine a use case of the apparatus based on the audio information and the other information. The audio processor is configured to adjust at least one audio processing scheme for the apparatus based on the determined use case. In other examples, a method and a computer program product are described.

Use case dependent audio processing

An apparatus comprising: a detector configured to determine at least one microphone is impaired by analyzing at least one audio signal from the at least one microphone; and an controller configured to determine an indicator based on the determination of the impairment of the at least one microphone; and configured to apply the indicator based on the determination of the impairment of the at least one microphone, such that the at least one audio signal is processed based on the indicator.
