Unity3d particle System + Audio Source = Music visualization

Very simple stuff, on the code:

usingUnityengine;usingSystem.Collections; Public classParticle_ocean:monobehaviour { PublicParticlesystem Particlesystem; Privateparticlesystem.particle[] Particlesarray;  Public intResolution = the;  Public floatspacing =0.5f;  Public floatNoisescale =0.2f;  Public float[] Heightscale; Private floatPERLINNOISEANIMX =0.01f; Private floatPerlinnoiseanimy =0.01f;  PublicGradient colorgradient;  Public float[] Heighttogoto; Private floatHeightgotospeed =20f; Private floatHeightrestorespeed =2f;  Public floatHeightgototime =1f;  Public floatHeightrestoretime =0.1f;  Public floatHeightclampmax =40f;  Public floatHeightclampmin =4f;  Public floatParticlesamplerate =0.05f; Private intFramecount =0; //Audio     PublicAudiosource Audio; Private float[] spectrum;  Public intSpectrumscale =60000; voidAwake () {application.targetframerate= -; }    voidStart () {Particlesarray=NewParticlesystem.particle[resolution *resolution]; Particlesystem.maxparticles= Resolution *resolution; Particlesystem.emit (resolution*resolution);        Particlesystem.getparticles (Particlesarray); Heightscale=New float[resolution]; Heighttogoto=New float[resolution]; Spectrum=New float[resolution]; Invokerepeating ("Updateheight",0, particlesamplerate); }    voidUpdate () { for(inti =0; I < resolution; i++) {             for(intj =0; J < resolution; J + +) {                floatZpos = Mathf.perlinnoise (i * Noisescale + perlinnoiseanimx, J * Noisescale + perlinnoiseanimy) *Heightscale[j]; Particlesarray [i* Resolution + J].color = colorgradient.evaluate (Zpos *0.025f); Particlesarray [i* Resolution + J].position =NewVector3 (i * spacing, zpos, J *spacing); }} perlinnoiseanimx+=0.01f; Perlinnoiseanimy+=0.01f;        Particlesystem.setparticles (Particlesarray, particlesarray.length);        Gotoheight (); RestoreTo2 ();    }    voidUpdateheight () {audio.
