Happy new year everybody, I decided to start the year off with a quick fun project :
http://www.shaderbytes.co.za/unity/new_year_music_visualizer/
It uses 3 particle systems but only one material. I am using both the raw signal as well as the FFT data.
enjoy.
(ps the song is by the band “porcupine tree” with the phenomenal Gavin Harrison on drums )
Hey @shaderbytes ! That is looking rather interesting. I’d like to get my hands on this 
Are you planning on taking this further/sell it via Asset Store?
@Thomas-Pasieka let me just clean up the project and i will post a link to download or attach it here in the thread Its not very complicated I just experimented with a few ideas until i made something that looked nice.
@Thomas-Pasieka ok cleaned up here you go :

As mentioned It was a quick prototype project ,there is one Gameobject named Waveform which plays the music and stores the samples then there are three GameObjects for each particle system. The particle Component settings for each of these are mostly the same as well as each particle script ( I duplicated them and made small tweaks )
In a nut shell :
On the WaveForm GameObject Inspector are 2 global sliders which are scalars for the sample strength of the raw data and the FFT data values. The Particle Scripts have there own individual sample scalars as well.
Particle1 does the spiral effect
Particle2 does the broken arcs and fireworks effect
Particle3 does the oscillating strobe effect
There are a few scalar settings exposed in the particle script inspectors but playing around with them is not that straight forward because part of what is happening on screen is been produced by Unity via the shuriken system and part by my code for example :
Particle 2 needs to have the “averagePeakScalar” value somewhere beneath 0.5 to produce the “fireworks” effect because this is what allows some particles to periodically escape the control of my code ( hence then been under control of the Unity Component )
Particle1 needs to have the "angleScalar " value very low like it currently is at 0.01 to produce those spirals.
anyway perhaps someday I should make a more robust product but for now this is what it is, I hope you get something out of it.
cheers
Thanks for the zip mate. Will have a play with this later!
