Abstract: A wearable loudspeaker unit comprises a loudspeaker, an audio reproduction processor, a wireless communications unit operable to communicate wirelessly with a base unit using a protocol that distinguishes the wearable loudspeaker unit from any other wearable loudspeaker units in communication with the base unit, and a user input interface operable to select one of a plurality of wearable loudspeaker unit wearing positions on a user's body; and the wireless communications unit is operable to transmit the selected wearing position of the wearable loudspeaker unit to the base unit, and is operable to receive audio data corresponding to the selected wearing position of the wearable loudspeaker unit from the base unit, and the audio reproduction processor is operable to output the received audio data through the loudspeaker.

Abstract: A method of audio processing an ensemble of sounds for output to a plurality of audio channels comprises the steps of evaluating an overall level of audio detail generated by the contributing sounds of the ensemble by analyzing metadata associated with respective sounds of the ensemble, the metadata being indicative of the contribution of a respective sound of the ensemble to an overall level of audio detail across the plurality of audio channels, and comparing the overall level of audio detail to a first threshold; and in which if the overall level of audio detail exceeds the first threshold, altering the ensemble of sounds to reduce the indicated contribution of the ensemble to the overall level of audio detail.
