The mix of tracks and sources created by the broadcaster would be a default, but the listener would have the abolity to create a different mix. For instance, in the case of a radio play with a mix of voices, sound effects and music, the listener could be offered an interface to control the relative volume of the voices to effects and music, or create a binaural mix tailored specifically to their taste. Such a feature would provide valuable personalisation of the radio experience, as well as significant accessibility enhancements.</p>
