Abstract:
Systems, methods, and devices for determining a frequency of a received audio signal. A device may include a microphone, a speaker, and a processor configured to perform operations including receiving, using the microphone, a first audio signal having a predetermined frequency. The operations may also include, for each test frequency of a plurality of test frequencies and for each test phase of a plurality of test phases, generating a second audio signal having the test frequency and the test phase, outputting, using the speaker, the second audio signal, receiving, using the microphone, a combined audio signal being a combination of the first audio signal and the second audio signal, determining an amplitude of the combined audio signal, and determining that the predetermined frequency is within a threshold range of the test frequency when the amplitude of the combined audio signal is below a threshold.

Claim (Index 1):
A portable electronic device comprising:\n a microphone; a speaker; and a processor communicatively coupled to the microphone and the speaker, wherein the processor is configured to perform operations comprising:\n receiving, using the microphone, a first audio signal having a predetermined frequency; and \n for each test frequency of a plurality of test frequencies and for each test phase of a plurality of test phases:\n generating a second audio signal having the test frequency and the test phase; \n outputting, using the speaker, the second audio signal; \n receiving, using the microphone, a combined audio signal being a combination of the first audio signal and the second audio signal; \n determining an amplitude of the combined audio signal; and \n determining that the predetermined frequency is within a threshold range of the test frequency when the amplitude of the combined audio signal is below a threshold.
