    • Disclosed are an audio coding apparatus encoding an audio signal by a lossless coding method or a lossy coding method and an audio decoding apparatus decoding the coded audio signal. The audio coding apparatus according to an embodiment comprises: an input signal type decision part which decides the type of an input signal based on the features of the input signal; a residual signal generation part which generates a residual signal based on the output signal of the input signal type decision part; and a coding part which processes lossless coding or lossy coding using the residual signal.
