DEVICE AND METHOD OF DECODING CODED AUDIO SIGNAL WITH LOW COMPUTING RESOURCES Russian patent published in 2018 - IPC G10L19/24 G10L21/38 

Abstract RU 2644135 C2

FIELD: physics.

SUBSTANCE: device of decoding an encoded audio signal (101) containing the band extension control data, indicating either the first mode of the harmonic band extension or the second mode of the harmonic band extension, includes: an input interface (100) for receiving an encoded audio signal; a processor (102) for decoding the audio signal (101) using the second harmonic mode of the band extension; a controller (104) to control the processor (102) for decoding the audio signal using the second mode of the harmonic band extension, even when the band extension control data indicate the first mode of the harmonic band extension for the encoded signal.

EFFECT: reducing the computational complexity of the audio signal processing method, which requires reduced memory resources.
