Acoustic characterization of an unknown microphone

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. ... Eva Automation Inc

Equalization based on acoustic monitoring

An audio/video (a/v) hub may measure the sound, corresponding to audio content, output by electronic devices. Then, the a/v hub may compare the measured sound to a desired acoustic characteristic at a first location in the environment based on the first location, a second location of the a/v hub, and an acoustic transfer function of the environment in at least a band of frequencies. ... Eva Automation Inc
