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 1):
An apparatus for generating a bandwidth extended signal from a bandwidth limited audio signal, the bandwidth limited audio signal comprising a plurality of consecutive bandwidth limited time blocks, each bandwidth limited time block comprising at least one associated spectral band replication parameter comprising a core frequency band and the bandwidth extended signal comprising a plurality of consecutive bandwidth extended time blocks, the apparatus comprising:\n a patch generator for generating a patched signal comprising an upper frequency band using a bandwidth limited time block of the bandwidth limited audio signal; wherein the patch generator is configured to perform a harmonic patching algorithm to acquire the patched signal; wherein the patch generator is configured to perform the harmonic patching algorithm for a current bandwidth extended time block of the plurality of consecutive bandwidth extended time blocks using a timely preceding bandwidth limited time block of the plurality of consecutive bandwidth limited time blocks of the bandwidth limited audio signal; a signal manipulator for manipulating a signal before patching or the patched signal generated using the timely preceding bandwidth limited time block using a spectral band replication parameter associated with a current bandwidth limited time block to acquire a manipulated patched signal comprising the upper frequency band; wherein 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; and a combiner for combining the bandwidth limited audio signal comprising the core frequency band and the manipulated patched signal comprising the upper frequency band to acquire the bandwidth extended signal.
