Some methods involve receiving, by a control system that is configured for implementing a plurality of renderers, audio data and listening configuration data for a plurality of listening configurations, each listening configuration of the plurality of listening configurations corresponding to a listening position and a listening orientation in an audio environment, and rendering, by each renderer and according to the listening configuration data, the received audio data to obtain a set of renderer-specific loudspeaker feed signals for a corresponding listening configuration. Each renderer may be configured to render the audio data for a different listening configuration. Some such methods may involve decomposing each set of renderer-specific loudspeaker feed signals into a renderer-specific set of frequency bands and combining the renderer-specific frequency bands of each renderer to produce an output set of loudspeaker feed signals.
