Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 2:
3. A system for decoding an encoded audio signal, comprising:
a receiver for receiving the encoded audio signal and determining an audio object from the encoded audio signal;
an audio object classification unit for classifying the audio object into at least one category based on rendering mode information, wherein the rendering mode information is part of metadata associated with the audio object;
a cluster assignment unit for computing a spatial distortion metric for the at least one category based on the rendering mode information, assigning a number of clusters to the at least one category based on the spatial distortion metric; and determining, for the at least one category, at least one cluster based on the metadata and the assigned number of clusters; and
a renderer for rendering the audio object based on the rendering mode information for the at least one cluster.
