To improve the perceived audio signal it is known to use a harmonics generator to create the illusion that the perceived audio signal comprises lower frequency signal parts than really available. The invention proposes an audio system in which not only the perceived so called ultra bass signals (for example 20 - 70 Hz) are improved but also of the signals in the frequency band between the ultra bass signal and the normal audio signal are created.
