Systems and methods for preserving headphone rendering mode (HRM) in object clustering are described. In an embodiment, an object-based audio data processing system includes a processor configured to receive a plurality of audio objects, wherein an audio object of the plurality of audio objects is associated with respective object metadata that indicates respective spatial position information and an HRM; determine a plurality of cluster positions by applying an extended hybrid distance metric to a spatial coding algorithm to calculate a partial loudness for each of the audio objects; render the audio objects to the cluster positions to form a plurality of clusters by applying the extended hybrid distance metric to the spatial coding algorithm to calculate object-to-cluster gains; and transmit the clusters to a spatial reproduction system.

Headphone rendering metadata-preserving spatial coding

An apparatus and method of blind detection of binauralized audio. If the input content is detected as binaural, a second binauralization may be avoided. In this manner, the user experience avoids audio artifacts introduced by multiple binauralizations.

Blind detection of binauralized stereo content

A method for steering binauralization of audio is provided. The method comprises steps of: receiving () an audio input signal, calculating () a confidence value indicating a likelihood that a current audio frame of the audio input signal comprises binauralized audio; determining () a state signal based on the confidence value; determining () a steering signal, based on the first confidence value, the state signal and an energy value of the audio frame; and generating () an audio output signal with steered binauralization by processing the audio input signal according to the steering signal.
