How to Analise your Fire Patch in Pure Data

Analysing Sound Design of Fire.

Fire is an oxidation process of different chemical elements that in combustion generates a chemical process.

It is important as a Sound Designer to understand and undertake the physical process that we want to emulate genaritin procedural audio. In my case I will use Andy’s Farnell Theory , development and implementation to analyse and generate an audio patch that will help me with my main goal with is the creation of an audio procedural patch that is attached to my particle system in Unity. 

Physical

What are the main differences between Audio and Sound?

Mathematical

How we can interpret the sounds by algoritmical functions such as Fourier Transform.

Psychological

Psychoacoustics, How human Auditory Perception is interpreting Sound

DESIGN

You need to be objective in your main goal App.

TECHNIQUE

Think About what path are undertaken to develop the App

ARTICULATION

Action the first test to your application.

Acoustics of Fire

Fire is Heat, Fuel, Oxygen & Chain Reaction.

When we are listen Fire there are two main sounds; The fuel material in oxidation process and the oxygen combustion, allowing the fire to become bigger or power. Which means that will use more fuel. 

Using Fourier Theorem we can have a feeling to use; noise generation, filters and envelopes we can crete the multiples layers of our sound design audio procedural patch.

The combustion uses a crackle noise that in some point is random because the combustion of the fire and physics do this; our brain relates this type of sounds as a permanent random noise that varies depending of the sizes of the chimney or just because of the characteristics of the combustion.

For counterpart, wishes and hissing sounds generated by multiples gasses may can be generated by pink or Whyte noise with some notch filter. 

“Popping or gaseous state explosions happen where the flammable gas and air mixture is suddenly at an ideal pressure” Andy Farnell, Designig Sound.
