Abstract:
An apparatus for generating a bandwidth extended signal from a bandwidth limited audio signal, the bandwidth limited audio signal The patch generator is configured to perform a harmonic patching algorithm to obtain the patched signal. The signal manipulator is configured for manipulating a signal before patching or the patched signal. The timely preceding bandwidth limited time block timely precedes the current bandwidth limited time block in the plurality of consecutive bandwidth limited time blocks of the bandwidth limited audio signal. The combiner is configured for combining the bandwidth limited audio signal having the core frequency band and the manipulated patched signal having the upper frequency band to obtain the bandwidth extended signal.

Claim (Index 3):
The apparatus in accordance with  claim 1 ,\n wherein the patch generator is configured for applying the harmonic patching algorithm to the timely preceding bandwidth limited time block using a bandwidth extension factor of two; wherein the patch generator is configured for generating from the core frequency band of the timely preceding bandwidth limited time block a first target frequency band of the current bandwidth extended time block; and wherein the patch generator is configured for applying a copy-up patching algorithm for copying up the first target frequency band of the current bandwidth extended time block generated from the core frequency band of the timely preceding bandwidth limited time block to a second target frequency band of the current bandwidth extended time block.
