    • PURPOSE: A device and a method of editing a multi-channel audio signal are provided to generate a multi-channel audio signal with 3D effects. CONSTITUTION: An output position determining unit (120) determines a position to which an object audio signal is outputted by using edit information of the object audio signal. A multi-channel object audio signal generating unit (130) generates a multi-channel object audio signal by allocating the object audio signal to a channel corresponding to the position to which the object audio signal is outputted. A multi-channel audio signal conversion unit (110) converts a first multi-channel audio signal into a second multi-channel audio signal corresponding to the multi-channel object audio signal. An audio mixing unit (140) generates a third multi-channel audio signal by mixing the multi-channel object audio signal to the second multi-channel audio signal.

    • PURPOSE: A multi-object audio signal encoding and decoding apparatus including additional information bit stream conversion and method thereof are provided to consume various audio objects by combining audio content through various methods. CONSTITUTION: A rendering information creation unit creates first rendering information for a multi-object audio signal. A rendering unit(303) creates spatial queue information for the multi-object audio signal based on second rendering information for the first rendering information and the multi-object audio signal. The second rendering information is transmitted from an encoding apparatus. The second rendering information includes preset ASI(Audio Scene Information) for the multi-object audio signal.

    • A method for generating a head related transfer function for sound externalization, an apparatus and a method for processing 3D audio signal using the same are provided to enhance presence of 3D audio signal by performing 3D audio signal processing by a head related transfer function modeled through a room impulse response measured by a sphere microphone from a space. A high presence multimedia reproduction system(30) includes a demultiplexing part(31), a video decoder(32), an audio decoder(33), and a 3D audio generating part(34). The demultiplexing part separates a multimedia data into a video data and an audio data. The video decoder decodes the separated video data into an original video signal. The audio decoder decodes the original audio signal by decoding the audio data. The 3D audio generating part generates a 3D audio signal about the decoded audio signal by a head related transfer function modeled through a multichannel room impulse response measured by a sphere microphone.
