Abstract: Provided is a sound event recognition method that may improve a sound event recognition performance using a correlation between difference sound signal feature parameters based on a neural network, in detail, that may extract a sound signal feature parameter from a sound signal including a sound event, and recognize the sound event included in the sound signal by applying a convolutional neural network (CNN) trained using the sound signal feature parameter.

Abstract: Provided is a stereophonic sound reproducing apparatus that applies a multi-rendering scheme to a channel sound signal and an object sound signal to enhance a stereophonic effect. A stereophonic sound reproducing method performed by the stereophonic sound reproducing apparatus may include receiving a channel sound signal based on a channel, an object sound signal based on an object, and metadata, and reproducing the channel sound signal based on a preset rendering scheme and reproducing, based on the metadata including a rendering scheme determined using the object sound signal, each object sound signal using the determined rendering scheme.

Abstract: A method of detecting a sound event includes receiving sound signals using one or more directional microphones, extracting a time interval of each of the sound signals, extracting time information and an azimuth of a sound event included in the sound signals during the extracted time interval, mixing the sound signals received from the directional microphones using the extracted time interval, and determining a direction of the sound event generated at a specific time from a mixed sound signal obtained through the mixing using the extracted time information and azimuth of the sound event.
