1. An audio processing apparatus, comprising:
a receiver circuit,
wherein the receiver circuit is arranged to receive audio data and render configuration data,
wherein the audio data comprises audio data for a plurality of audio components,
wherein the render configuration data comprises audio transducer position data for a plurality of audio transducers;
a renderer circuit,
wherein the renderer circuit is arranged to generate audio transducer signals for the plurality of audio transducers from the audio data,
wherein the renderer circuit is arranged to render the plurality of audio components in accordance with a plurality of rendering modes;
a render controller circuit, wherein the render controller circuit is arranged to select at least one rendering mode for the renderer circuit from the plurality of rendering modes, in response the audio transducer position data,
wherein the renderer circuit is configured to use different ones of the plurality of rendering modes for different transducer subsets of the plurality of audio transducers,
wherein the plurality of rendering modes comprises at least a stereophonic rendering mode and an ambisonic rendering mode,
wherein the renderer circuit is configured to select different rendering modes for each of the different transducer subsets,
wherein the render controller circuit is arranged to select at least one rendering mode for a first audio transducer of the plurality of audio transducers in response to a position of the first audio transducer relative to a predetermined position for the first audio transducer,
wherein the renderer circuit is configured to use different rendering modes for the at least two audio components,
wherein the receiver circuit is configured to receive audio type indication data,
wherein the audio type indication data is indicative of an audio type of at least a first one of the audio components,
wherein the render controller circuit is configured to select a first rendering mode for the first audio component in response to the audio type indication data,
wherein the renderer circuit is configured to use different rendering modes for different audio components for the first audio transducer,
wherein the render controller circuit is configured to select rendering modes from the plurality of rendering modes for each of the audio components for the first audio transducer,
wherein the receiver circuit is arranged to receive rendering position data for the audio components,
wherein the render controller circuit is arranged to select the rendering modes in response to the rendering position data.
