摘要： An apparatus, a method and a computer program product are provided for use in rendering audio. An apparatus is configured for: receiving a first audio signal representative of a virtual sound scene, wherein the first audio signal is configured for rendering on an arrangement of loudspeakers to a user; determine a first portion of the virtual sound scene to be rendered on headphones of the user; generating a second audio signal representative of the first portion of the virtual sound scene; determining a second portion of the virtual sound scene to be rendered on the arrangement of loudspeakers; generating a third audio signal, representative of the second portion of the virtual sound scene; and wherein the second and third audio signals are generated such that, when rendered, an augmented version of the virtual sound scene is rendered to the user.

摘要： Method, apparatus and computer program product of direct reproduction/rendering of parametric spatial audio with sound-field related parametrization using a soundbar. The parametric spatial audio is reproduced directly with the soundbar without intermediate formats. Positioning of the audio is performed directly based on metadata associated with audio signals. Audio signals are received, metadata associated with those signals are obtained, and the signals are divided into direct and ambient parts based on the metadata. The direct part can be reproduced using panning and beamforming. The ambience is reproduced by creating ambient beams that radiate the sound in multiple directions using reflection. As a result, the listener receives the sound via multiple reflections and perceives the sound as enveloping. The soundbar signals reproduce the direct and ambient parts by merging to produce an output.
