摘要：
Provided is an audio signal encoding method including transforming an input signal from a time domain to a time/frequency domain using a first transformation method, extracting a stereo parameter from a signal of the time/frequency domain, encoding the stereo parameter, and down-mixing the signal of the time/frequency domain, transforming each of sub-bands of the down-mixed signal to a frequency domain by using a second transformation method, and encoding the signal of the frequency domain in the frequency domain.
