摘要： Disclosed is an audio signal processing device. The audio signal processing device includes a receiving unit configured to receive a first audio signal corresponding to a sound collected by a first sound collecting device and a second audio signal corresponding to a sound collected by a second sound collecting device, a processor configured to process the second audio signal based on a correlation between the first audio signal and the second audio signal, and an output unit configured to output a processed second audio signal. The first audio signal is a signal for reproducing an output sound of a specific sound object, and the second audio signal is a signal for ambience reproduction of a space in which the specific sound object is positioned.

摘要： Disclosed is an audio signal processing device for performing binaural rendering on an input audio signal. The audio signal processing device includes a reception unit configured to receive the input audio signal, a binaural renderer configured to generate a 2-channel audio by performing binaural rendering on the input audio signal, and an output unit configured to output the 2-channel audio. The binaural renderer performs binaural rendering on the input audio signal based on a distance from a listener to a sound source corresponding to the input audio signal and a size of an object simulated by the sound source.

摘要： An audio signal processing device comprises: a receiver for receiving an input audio signal; a processor for generating loudness metadata corresponding to the input audio signal; and an outputter for transmitting the loudness metadata generated by the processor. The processor is configured to acquire loudness information analyzed from input content, acquires loudness information about the input audio signal by measuring the loudness of the input audio signal, generates the loudness metadata by converting the loudness information, and transmits, through the outputter, the generated loudness metadata to an output device for outputting the input audio signal.

摘要： An audio signal processing apparatus including a receiving unit receiving an input audio signal, a processor generating an output audio signal reproducing a virtual sound source corresponding to the input audio signal in a virtual space, and an output unit outputting an output audio signal generated by the processor is disclosed. The processor may obtain spatial information related to the virtual space including a virtual sound source corresponding to the input audio signal and a listener, filter the input audio signal based on a location of the virtual sound source and the spatial information to generate at least one reflected sound corresponding to each of at least one mirror plane in the virtual space, obtain a relative location of a virtual reflect sound source with respect to a location and a view-point of the listener, based on information of the view-point of the listener and a location of the virtual reflect sound source corresponding to each of the at least one reflected sound, and binaural render the at least one reflected sound, based on the relative location of the virtual reflect sound source corresponding to each of the at least one reflected sound.
