Abstract
Examples described herein involve validating motion of a microphone during calibration of a playback device. An example implementation involves receiving motion data indicating movement of a recording device while the recording device was recording a calibration sound emitted by one or more playback devices in a given environment during a calibration period. The example implementation also involves determining that sufficient vertical translation of the recording device occurred during the calibration period. The example implementation further involves determining that sufficient horizontal translation of the recording device occurred during the calibration period. The implementation involves sending, by the computing device to one or more playback devices, a message indicating that sufficient translation of the recording device occurred during the calibration period in vertical and horizontal directions.
