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： 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 apparatus is provided. The audio signal processing apparatus includes an input terminal receiving an input audio signal, a processor obtaining a difference between a playback loudness of the input audio signal and a desired loudness thereof and correcting a frequency band spectrum of an output audio signal for each of a plurality of frequency bands based on the difference between the playback loudness and the desired loudness of the input audio signal and a relationship between a loudness and a sound pressure for each of the plurality of frequency bands, and an output terminal outputting the output audio signal. The playback loudness is a loudness of the output audio signal when the input audio signal is output without the correction.
