The third control of the VITALIZER section determines the ratio between	19	Process
BASS and MID-HITUNE to the original signal. The HARMONICS control is not

affected by the PROCESS control.

The PROCESS control determines the damping intensity of dominant mid frequencies. This allows rapid adaptation to the loudness curves (Fletcher- Munson curves, curves of equal loudness).

The human ear perceives the audio frequency spectrum at varying sound pressure levels very differently. Perception is by no means »linear«. The VITALIZER alters the frequency spectrum in such a way that the balance is maintained between all frequency ranges even at varying monitor volumes. For the human ear, the sound is more pleasant and easier to perceive than the original. In other words, increasing the PROCESS value also increases the intensity of the MID-HITUNE filter and the BASS filter, whilst dominant mid frequencies are damped by amplitude-controlled phase shiftings. This improves the perception of loudness, clarity and the bass punch, i.e. the strength and fullness of the audio signal.

Fig. 9:

The dotted line shows frequency responses for a soft Bass (SOFT) at varying PROCESS and a MID-HITUNE of 3.5 kHz.

The solid line shows the phase responses, which always drift only a few degrees if the PROCESS inten- sity is increased.

The diagram shows very clearly that the mid attenuation gets stronger as the PROCESS value increases.
