One or more operating conditions of a device such as a mobile phone are determined (802). A selection of a mode of operation of the device from at least a first mode and a second mode is facilitated (806, 808) based on the one or more operating conditions of the device such as the time delay between times of arrival of the audio signals (804). In the first mode; the device is configured to detect an operation input received from an audio source based on two or more audio sensors of the device. In the second mode, the device is configured to detect the operation input based on at least one of the two or more audio sensors and at least one non-audio sensor of the device. |
