Abstract:
An audio signal synthesizer generates a synthesis audio signal having a first frequency band and a second synthesized frequency band derived from the first frequency band and comprises a patch generator, a spectral converter, a raw signal processor and a combiner. The patch generator performs at least two different patching algorithms, each patching algorithm generating a raw signal. The patch generator is adapted to select one of the at least two different patching algorithms in response to a control information. The spectral converter converts the raw signal into a raw signal spectral representation. The raw signal processor processes the raw signal spectral representation in response to spectral domain spectral band replication parameters to obtain an adjusted raw signal spectral representation.

Claim (Index 15):
A non-transitory digital storage medium having a computer program stored thereon to perform the method for generating a synthesis audio signal comprising a first frequency band and a second replicated frequency band derived from the first frequency band, comprising:\n performing at least two different patching algorithms, wherein each patching algorithm generates a raw signal comprising signal components in the second replicated frequency band using an audio signal comprising signal components in the first frequency band, and wherein the patching is performed such that one of the at least two different patching algorithms is selected in response to a control information for a first time portion and the other of the at least two different patching algorithms is selected in response to the control information for a second time portion different from the first time portion to acquire the raw signal for the first and the second time portion; converting the raw signal into a raw signal spectral representation; processing the raw signal spectral representation in response to spectral domain spectral band replication parameters to acquire an adjusted raw signal spectral representation; and combining the audio signal comprising signal components in the first band or a signal derived from the audio signal with the adjusted raw signal spectral representation or with a further signal derived from the adjusted raw signal spectral representation to acquire the synthesis audio signal, when said computer program is run by a computer.
