  • Acoustic characterization of an unknown microphone
    Patent number: 10200800
    Abstract: An electronic device with a microphone is used to determine a transfer function of an environment (and, more generally, an acoustic characteristic). In particular, the electronic device may use the microphone to perform acoustic measurements when the electronic device is proximate to a speaker in the environment. Then, based on the acoustic measurements and a first predetermined transfer function of the speaker, the electronic device may calculate a transfer function of the microphone in a band of frequencies. Moreover, the electronic device may use the microphone to perform additional acoustic measurements in the environment that includes the speaker. Next, based on the additional acoustic measurements, the transfer function of the microphone and a second predetermined transfer function of the speaker, the electronic device may determine the transfer function of the environment in the same or a different band of frequencies.
