Disclosed is an apparatus and method for augmenting training data using a notch filter. The method may include obtaining original data, and obtaining training data having a modified frequency component from the original data by filtering the original data using a filter configured to remove a component of a predetermined frequency band.

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.
