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.
