PROBLEM TO BE SOLVED: To provide a method and a device which efficiently encode/decode a speech signal and/or an audio signal.SOLUTION: A method and a device encode/decode a speech signal and/or an audio signal. The device comprises a first domain conversion unit, a frequency domain encoding unit, and a multiplexing unit to encode the speech signal and/or the audio signal. The device comprises a demultiplexing unit, a frequency domain decoding unit, and a second domain inverse conversion unit to decode the speech signal and/or the audio signal. The method and the device can efficiently encode/decode each of the speech signal, the audio signal, and the mixed signal of the speech signal and the audio signal, and further enhance quality of sound even by using a small number of bits. |
