Document Type and Number:
WIPO Patent Application WO/2020/185025
Kind Code:
A1
Abstract:
An audio signal processing device comprises: a receiving unit for receiving an input audio signal; a processor for generating loudness metadata corresponding to the input audio signal; and an output unit for transmitting the loudness metadata generated by the processor. The processor acquires 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 output unit, the generated loudness metadata to an output device for outputting the input audio signal.
