Abstract:
Systems and method are disclosed for facilitating efficient calibration of filters for correcting room and/or speaker-based distortion and/or binaural imbalances in audio reproduction, and/or for producing three-dimensional sound in stereo system environments. According to some embodiments, using a portable device such as a smartphone or tablet, a user can calibrate speakers by initiating playback of a test signal, detecting playback of the test signal with the portable device's microphone, and repeating this process for a number of speakers and/or device positions (e.g., next to each of the user's ears). A comparison can be made between the test signal and the detected signal, and this can be used to more precisely calibrate rendering of future signals by the speakers.

Claim (Index 35):
A portable device for calibrating speakers for a particular environment, the portable device comprising:\n a microphone; a processor; and a non-transitory memory storing instructions that when executed by the processor of the portable device cause the portable device to perform operations comprising:\n providing instructions for positioning the microphone of the portable device at a first location in an environment; \n initiating first playback by an audio source of a first piece of audio content over a speaker; \n detecting the first playback of the first piece of audio content by the microphone at the first location; \n providing instructions for positioning a microphone at a second location in the environment, the second location being different from the first location; \n initiating second playback by the audio source of the second piece of audio content over the speaker; \n detecting the second playback of the second piece of audio content using the microphone at the second location; and determining, based at least in part on the detected first playback of the first piece of audio content and the detected second playback of the second piece of audio content, one or more adjustments to be applied to additional audio content before additional audio content playback by the speaker, wherein determining the one or more adjustments comprises:\n accessing information relating to the speaker; determining the one or more adjustments using, at least in part, the information relating to the speaker; and \n applying the one or more adjustments to the additional audio content before it is played by the speaker.
