Sub Harmonic
- the Sub Harmonic Synthesizer is a particular process, already introduced in the
first part of the manual, that isn’t actually related to the RMS compression one.
The Sub Harmonic Synthesizer is intended to be an “extra” process available to the user, where the
RMS Compressor is chosen for processing a source addressed to a “background” use, as in clubs.
It is possible to have synthesized bass in order to extend the band. Also when the
musical program is poor of harmonics in the low frequencies, it can help in improving the quality of
the background music and to gain a "heavier" or more vibrant sound.
The Sub Harmonic Synthesizer is a process synthesizing the first lower harmonic of the
frequencies ranging from 40Hz to 500Hz, detected in the original signal.
This means that there in the original signal, are detected frequencies from 40Hz to 500Hz, sub
harmonics from 20Hz to 250Hz are generated.
Figure F
As can be seen in the Figure F, however, the synthesized sub harmonics are not generated in the
Low harmonics’ band with the same amplitude, but with a Peak on 65Hz or on 90Hz and then with
decreasing amplitude going up from 65Hz/90Hz to 250Hz and down to 20Hz.
