  • ENCODING/DECODING AUDIO AND/OR SPEECH SIGNALS BY TRANSFORMING TO A DETERMINED DOMAIN
    Publication number: 20170032800
    Abstract: A method and apparatus to encode and/or decode a speech signal and/or an audio signal. The apparatus includes a first domain transforming unit, a frequency domain encoding unit, and a multiplexing unit to encode the speech signal and/or an audio signal. The apparatus includes a demultiplexing unit, a frequency domain decoding unit, and a second domain inverse transformation unit to decode the speech signal and/or the audio signal. The method and apparatus are capable of effectively encoding or decoding all of a speech signal, an audio signal, and a mixed signal of a speech signal and an audio signal, and improving the quality of sound by using a small number of bits.
