Abstract: The invention relates to an apparatus (1) for improving a stereo audio signal of an FM stereo radio receiver (10). It is suggested to employ components of a standard HE-ACC v2 decoder (40) in such apparatus (1) to efficiently recover the stereo audio signal (L\R?) while also exhibiting good signal quality. To that end, parametric stereo parameters (15) shall be quantized and submitted to such decoder (40) together with a mono-downmix signal (25). The decoder (25) can then easily recover the parametric stereo parameters (15) by de-quantizing them via a simple lookup table, and finally creating the stereo output signal (L?R?) from the de-quantized parametric stereo parameters and the mono-downmix signal (25). The apparatus (1) further includes a parameter estimation stage (5) which may again be embodied on the basis of components of a standard HE-ACC v2 encoder (65).
