摘要：
An apparatus for decoding an encoded audio signal (101) comprising bandwidth extension control data indicating either a first harmonic bandwidth extension mode or a second non-harmonic bandwidth extension mode, comprises: an input interface (100) for receiving the encoded audio signal comprising the bandwidth extension control data indicating either the first harmonic bandwidth extension mode or the second non-harmonic bandwidth extension mode; a processor (102) for decoding the audio signal (101) using the second non-harmonic bandwidth extension mode; and a controller (104) for controlling the processor (102) to decode the audio signal using the second non-harmonic bandwidth extension mode, even when the bandwidth extension control data indicates the first harmonic bandwidth extension mode for the encoded signal.
