Abstract: The present invention provides a vehicle including a sound control device. The sound control device comprises: a sound object extraction module which extracts one or more audio objects from an audio signal received from an outdoor microphone provided outside the vehicle and an indoor microphone provided inside the vehicle; a sound object renderer which performs rendering with an audio function by using an audio object signal; a genre recognizer which analyzes the received audio signal to classify a genre and generates a probability value for each genre; a volume measurement unit which measures the size of each of the audio objects and visualizes the measured sizes of the audio objects; and a volume control unit which applies a different volume to each of the audio objects, on the basis of the genre classified by the genre recognizer.

Abstract: The present invention provides a vehicle comprising a sound control device. A sound control device, according to one embodiment of the present invention, comprises: a sound object extraction module that extracts at least one audio object from an audio signal received from at least one of an outdoor microphone provided outside a vehicle and an indoor microphone provided inside the vehicle; and a sound object renderer that performs rendering with an audio function by using the audio object signal extracted by the sound object extraction module.

Abstract: Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device and an image display apparatus including the same include: a converter configured to convert of frequency of an input stereo audio signal; a primary component analyzer configured to perform primary component analysis based on a signal from the converter; a feature extractor configured to extract a feature of a primary component signal based on a signal from the primary component analyzer; an envelope adjustor configured to perform envelope adjustment based on prediction performed on the basis of a deep neural network model; and an inverse converter configured to inversely convert a signal from the envelope adjustor to output an upmix audio signal of multi-channel. Accordingly, when upmixing the downmix stereo audio signal to a multichannel audio signal, spatial distortion can be improved.
