FIELD: radio engineering, communication.
SUBSTANCE: disclosed is an apparatus for coding a portion of an audio signal to obtain an encoded audio signal for the portion of the audio signal. The apparatus includes a transient detector for detecting whether a transient signal is located in the portion of the audio signal to obtain a transient detection result. The apparatus also includes an encoder stage for performing a first encoding algorithm on the audio signal to obtain a first audio signal quality result for said portion of the audio signal, wherein the first encoding algorithm has a first characteristic, and for performing a second encoding algorithm on the audio signal to obtain a second audio signal quality result, wherein the second encoding algorithm has a second characteristic which is different from the first characteristic.
EFFECT: high efficiency of encoding audio signals by defining the encoding algorithm based on audio signal quality result detection and transient detection.
