摘要: Disclosed is a device for processing an audio signal, which renders an audio signal. The device for processing an audio signal includes a processor. The processor receives metadata including an audio signal and first element reference distance information and renders a first element signal on the basis of the first element reference distance information, wherein the first element reference distance information indicates the reference distance of an element signal. The audio signal is capable of including a second element signal which may be simultaneously rendered with the first element signal, and the metadata is capable of including second element distance information indicating the distance of the second element signal. The number of bits required for representing the first element reference distance information is smaller than the number of bits required for representing the second element distance information.

摘要: An embodiment of the present disclosure provides an audio signal processing device configured to transmit/receive an audio signal to/from an external acoustic output device that includes a microphone and an acoustic output means, including a transmission/reception module configured to transmit/receive a signal to/from the external acoustic output device, and a processor configured to control an operation of the transmission/reception module, wherein the processor transmits an audio output signal to the external acoustic output device through the transmission/reception module, receives, through the transmission/reception module, an input signal to which an external acoustic collected through the microphone is converted while the acoustic output means outputs an acoustic based on the audio output signal, and compares the audio output signal with the input signal to determine whether a user wears the acoustic output means of the external acoustic output device.

摘要: Disclosed is an audio signal processing device. The audio signal processing device includes a receiving end configured to receive a 2-channel stereo signal and a processor configured to process the 2-channel stereo signal. The processor is configured to filter the 2-channel stereo signal using a spatial distortion removal filter and output the filtered 2-channel stereo signal to a speaker including two or more channels. The spatial distortion removal filter is a filter for offsetting distortion that occurs when the output signal is transmitted from the speaker to a listener, and includes an ipsilateral filter applied to an ipsilateral signal of the 2-channel audio signal and a contralateral filter applied to a contralateral signal of the 2-channel audio signal.
