ABSTRACT:
To improve the perceived audio signal, it is known to use a harmonics generator to create the illusion that the perceived audio includes lower frequency signal parts than really available. In addition to improving the perceived so called ultra bass signals (for example 20-70 Hz) also the signals in the frequency band between the ultra bass signal and the normal audio signal are improved.
