Abstract: A loudness normalization method includes receiving data for playback of content from a server in response to a user's request to play back the content; normalizing the loudness of the content by adjusting the volume output level of a player using volume level metadata of the content included in the received data; and providing the content by playing audio of the content based on the adjusted volume output level of the player.

Abstract: A method for processing an audio signal includes setting target loudness; receiving metadata of an audio signal from a server; and adjusting the loudness of the audio signal by using the received metadata, so that the loudness of the audio signal corresponds to the set target loudness.

Abstract: The present invention relates to an apparatus and a method for processing an audio signal, and more particularly, to an apparatus and a method for efficiently rendering a higher order ambisonics signal. To this end, provided are an audio signal processing apparatus, including: a pre-processor configured to separate an input audio signal into a first component corresponding to at least one object signal and a second component corresponding to a residual signal and extract position vector information corresponding to the first component from the input audio signal; a first rendering unit configured to perform an object-based first rendering on the first component using the position vector information; and a second rendering unit configured to perform a channel-based second rendering on the second component and an audio signal processing method using the same.
