The apparatus also comprises a signal processor configured to process the transient-reduced audio signal to obtain a processed version of the transient-reduced audio signal.; The apparatus also comprises a transient-signal-re-inserter configured to combine the processed version of the transient-reduced audio signal with a transient signal representing, in an original or processed form, a transient content of the transient signal portion.en621006patent2009014875920090231563
