Provided are an apparatus and a method for encoding and decoding audio signals, in which when determining a masking threshold according to a psychoacoustic model, accurate results may be obtained for a short window-based audio signal as well as for a long window-based audio signal. The apparatus for encoding audio signals according to the present invention comprises a masking threshold determining unit configured to determine, on the basis of a frame length of a first window having a divided audio signal, a masking threshold for a second window that has a different frame length from that of the first window.

Method and apparatus for encoding and decoding audio signal

A method of processing a sound signal includes obtaining a phase difference or a time difference between sound signals received at both ears; determining a level difference between the sound signals based on the phase difference or time difference; determining gains of the sound signals to be output to both ears based on the level difference; and outputting the sound signals based on the determined gains.
