摘要： An apparatus and method of encoding an audio signal and an apparatus and method of decoding an audio signal. The audio decoding method includes: generating an audio signal by decoding an input signal, and transforming an original waveform of the generated audio signal into a compensation waveform that is compensated for an acoustic resonance effect in the audio signal. Therefore, an audio signal having excellent sound quality without an amplified middle band can be heard via earphones, headphones, or a phone earpiece by using an inverse compensation waveform to compensate an ERP-DRP resonance effect, which is an acoustic resonance effect generated due to the structure of the human ear.
