Various arrangements for providing audio calibration are presented. A remote control may determine that it is in position for an audio-based command to be received by the remote control from a user. Via a condenser microphone incorporated as part of the remote control, a calibration sound may be output. The condenser microphone may receive the output the calibration sound in the form of a reflected sound that is an acoustic reflection of the calibration sound. The remote control may analyze an amount of time that has elapsed between outputting the calibration sound and receiving the reflected sound to determine a distance between the condenser microphone and the user. One or more audio input settings may be configured that are used for modifying audio received by the condenser microphone based on the determined distance.
