Systems and methods for calibrating speakers
First Claim
1. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a portable electronic device, cause the portable electronic device to perform operations comprising:
- establishing, by the portable electronic device, a network connection between the portable electronic device and a network-connected speaker system;
rendering, via a user interface of the portable electronic device, instructions for repositioning the portable electronic device within an environment of the network-connected speaker system;
sending from the portable electronic device to the network-connected speaker system, via the network connection, a signal initiating playback of a piece of audio content by the network-connected speaker system, the signal comprising an audio file corresponding to the piece of audio content;
detecting a first playback of the piece of audio content by a microphone of the portable electronic device at a first location within environment;
detecting a second playback of the piece of audio content by the microphone of the portable electronic device at a second location within the environment;
determining, based at least in part on the detected first playback of the piece of audio content and the detected second playback of the piece of audio content, one or more adjustments to be applied to additional audio content before additional audio content playback by the network-connected speaker system, wherein determining the one or more adjustments comprises;
accessing a system information file of the portable electronic device to determine a transfer function of the microphone, anddetermining the one or more adjustments using, at least in part, the transfer function of the microphone; and
applying the one or more adjustments to the additional audio content before it is played by the network-connected speaker system.

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.
