Abstract
Examples described herein involve calibration of a microphone of a network device based on a first signal detected by the microphone of the network device and a second audio signal detected by a microphone of the playback device. While the network device is positioned within a predetermined physical range of a microphone of a playback device, a microphone of the network device may detect a first audio signal. The network device may also receive data indicating a second audio signal detected by the microphone of the playback device. Based on data indicating the first audio signal and the data indicating the second audio signal, the network device may identify a microphone calibration algorithm, and apply the microphone calibration algorithm when performing a calibration function associated with the playback device. Similar functions may also be performed by a computing device, such as a server to coordinate calibration of the microphone of the network device.
