Claim 16:
17. The audio decoder of claim 13, wherein the second decoding processor comprises:
a time domain low band decoder configured for decoding to obtain a low band time domain signal having a first sampling rate;
an upsampler configured for upsampling the low band time domain signal to obtain an upsampled low band time domain signal having a second sampling rate being higher than the first sampling rate, the upsampled low band time domain signal representing the low band of the decoded time domain second audio signal portion;
a time domain bandwidth extension decoder configured for synthesizing the high band of the decoded time domain second audio signal portion having the second sampling rate using the low band time domain signal; and
a mixer configured for mixing the high band of the decoded time domain second audio signal portion having the second sampling rate and the upsampled low band time domain signal having the second sampling rate to obtain the decoded time domain second audio signal portion.
