1. A method for managing incoming audio signals, the method comprising:
automatically obtaining, by a microphone, a first recurrent sound from a device;
subsequent to the first recurrent sound recurring a threshold number of occurrences, generating a reference representation of the first recurrent sound;
detecting, by the microphone, a second sound from the device;
in response to the second sound being within a threshold difference of the reference representation of the first recurrent sound, updating the reference representation; and
storing the updated reference representation.
