An audio processing apparatus includes a receiver configured to receive audio data including audio components and render configuration data including audio transducer position data for a set of audio transducers. A renderer is configured to generate audio transducer signals for the set of audio transducers from the audio data, and to render audio components in accordance with rendering modes. A render controller is configured to select a rendering mode for the renderer based on the audio transducer position data. The renderer is configured to employ different rendering modes for different subsets of the set of audio transducers and the render controller is configured to independently select rendering modes for each of the different subsets of the set of audio transducer including selecting the rendering mode for a first audio transducer in response to a position of the first audio transducer relative to a predetermined position for the first audio transducer.
