What is Harmonic Prism?
In 99% of cases, when we play any particular musical note, the Harmonics associated with it are related to each other by a particular mathematical relation;
The Harmonics in a standard waveform are an integral multiple of the fundamental.
For example, let's say we are playing a saw wave at 440Hz. In that case,
The Fundamental frequency/First Harmonic will be at 440Hz,
The 2nd Harmonic will be at 440*2 = 880Hz
The 3rd Harmonic will be at 440*3 = 1320Hz
The 4th Harmonic will be at 440*4 = 1760Hz
and so on...
These are called the harmonic frequencies.
But what happens when these Harmonics are played at another frequency value? In that case, those harmonics are referred to as Inharmonic frequencies.
Harmonic Prism is the unit that performs this function, It shifts the Harmonic frequencies into inharmonic range. You have the freedom to choose what frequency you wanna shift, to what extent, and in which direction.
Why is Harmonic Prism so important?
For Music producers who deal with instruments on regular basis, this function may not sound so intriguing. But for Game and Film sound designers, this is a goldmine.
When you shift certain harmonics into inharmonic range, it introduces the metallic and dark character into sound. This character can be very useful in creating Dark bells, Lead, Pads, cinematic FX, SFX, and subshifts.
This function can save you a lot of time and money on field recordings.
Exploring Harmonic Prism Functions
Now that you know how the Harmonic Prism works let's look at how to use it in sound design.
Harmonic Prism has its own dedicated shaping window which you can access from the Shaping section of Harmor.
In the Prism shaping, the Harmonics are divided according to the octaves. The window can be divided into 2 sections -100 to 0(Below the center) and 0 to +100(Above the center).
