Examples described herein involve calibrating a playback device. An example implementation involves causing a network device to display a guide to calibrate at least one playback device, the guide comprising an indication that the network device is to be moved during a given time. The example implementation also involves detecting, via the network device during the given time, an audio signal played by the at least one playback device. The example implementation further involves causing, via the network device, identification of an audio processing algorithm based on data indicating the detected audio signal.
