Abstract
An audio codec system and an encoding method using the same are provided. According to the method, encoding and decoding processes are repeatedly performed so as to determine optimized coding parameters when analog audio signals being inputted are encoded. The processes of encoding and decoding inputted analog audio signals using initial coding parameters, and computing new parameters using a differential computed during the encoding process are repeatedly performed.
