Apparatus and method for encoding and decoding of integrated speech and audio

A method for decoding an input signal executed by a computer, the method comprising:

• determining a characteristic of the encoded input signal in a bitstream whether the encoded input signal has an audio characteristic or a speech characteristic;
• and
• decoding the encoded input signal based on the characteristic, using either a first decoder based on a time-domain coding scheme or a second decoder based on a transform-coding scheme,
• wherein the encoded input signal is transmitted to the first decoder or the second decoder according to the characteristic of the input signal having the audio characteristic or the speech characteristic.

A method for decoding an input signal executed by a computer, the method comprising:

• determining a characteristic of the encoded input signal in a bitstream whether the encoded input signal has an audio characteristic or a speech characteristic;
• decoding the encoded input signal by one of
• decoding a core band of the encoded input signal using a first decoder based on a time-domain coding scheme, when the input signal has the speech characteristic;
• or
• decoding a core band of the encoded input signal using a second decoder based a transform-coding scheme, when the input signal has the audio characteristic;
• or
• wherein the encoded input signal is transmitted to the first decoder or the second decoder according to the characteristic of the input signal having the audio characteristic or the speech characteristic.

An apparatus for encoding an input signal executed by a computer, the apparatus comprising:

• one or more processor is configured to:
• determine a characteristic of the input signal whether the input signal has an audio characteristic or a speech characteristic
• encode the input signal based on the characteristic, using either a first encoder based on a time-domain coding scheme or a second encoder based on a transform-coding scheme,
• generate a bitstream including an encoding result of the input signal.
• wherein the input signal is transmitted to the first encoder or the second encoder according to the characteristic of the input signal being the audio characteristic or the speech characteristic.
