Abstract

Examples described herein involve calibrating a playback device for a playback environment based on audio signals detected by a microphone of a network device as the network device moves about the playback environment. While the playback device is playing a first audio signal and the network device is moving within the playback environment from a first physical location to a second physical location, the network device may detect by a microphone of the network device, a second audio signal. The network device may then identify an audio processing algorithm based on data indicating the second audio signal, and transmit to the playback device, data indicating the identified audio processing algorithm. Similar functions may also be performed by the playback device being calibrated or a computing device, such as a server to coordinate calibration of the playback device.
