1. A method comprising:
- determining at least one microphone is impaired by analysing at least one audio signal from the at least one microphone, wherein analysing the at least one audio signal from the at least one microphone comprises;
generating a histogram comparing a power level for the at least one audio signal from the at least one microphone over time;
determining whether the generated histogram has collected valid data to reflect the power level for the at least one audio signal;
detecting at least one histogram peak and a value greater than a defined threshold based on the collected valid data; and
determining a position of the detected at least one histogram peak occurs outside a defined normal operational range for the microphone, the defined normal operational range indicating when the at least one microphone is operating correctly or as expected;
determining an indicator based on the determination of the impairment of the at least one microphone; and
applying 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.

Abstract
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.

18. An apparatus comprising:
-
a detector configured to determine at least one microphone is impaired by analysing at least one audio signal from the at least one microphone, wherein by analysing the at least one audio signal from the at least one microphone, the detector is further configured to; generate a histogram comparing a power level for the at least one audio signal from the at least one microphone over time; determine whether the generated histogram has collected valid data to reflect the power level for the at least one audio signal; detect at least one histogram peak and a value greater than a defined threshold based on the collected valid data; and determine a position of the detected at least one histogram peak occurs outside a defined normal operational range for the microphone, the defined normal operational range indicating when the at least one microphone is operating correctly or as expected; 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.

19. An apparatus comprising at least one processor and at least one memory including computer code for one or more programs, the at least one memory and the computer code configured to with the at least one processor cause the apparatus at least to:
-
determine at least one microphone is impaired by analysing at least one audio signal from the at least one microphone, wherein by analysing the at least one audio signal from the at least one microphone, the at least one processor further causes the apparatus to; generate a histogram comparing a power level for the at least one audio signal from the at least one microphone over time; determine whether the generated histogram has collected valid data to reflect the power level for the at least one audio signal; detect at least one histogram peak and a value greater than a defined threshold based on the collected valid data; and determine a position of the detected at least one histogram peak occurs outside a defined normal operational range for the microphone, the defined normal operational range indicating when the at least one microphone is operating correctly or as expected; determine an indicator based on the determination of the impairment of the at least one microphone; and 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.
