Claim 11:
12. The audio decoder of claim 10, wherein the linear prediction domain decoder comprises:
the ACELP decoder, a low band synthesizer, an upsampler, the time domain bandwidth extension processor or a second combiner, wherein the second combiner is configured for combining an upsampled low band signal and a bandwidth-extended high band signal to acquire a full band ACELP decoded mono signal;
a TCX decoder and an intelligent gap filling processor to acquire a full band TCX decoded mono signal;
a full band synthesis processor for combining the full band ACELP decoded mono signal and the full band TCX decoded mono signal, or
wherein a cross-path is provided for initializing the low band synthesizer using information derived by a low band spectrum-time conversion from the TCX decoder and the IGF processor.
