4M particles reacting Music – Real Time FFT using 65536 sample on MP3 stream

This is a sound visualization all made on GPU. Using DirectShow.net to grab samples of mp3 audio fille in real-time. Using Cloo GPU accelerated FFT on 65536 Samples in real-time to achieve frequency. Using CUDA to move particles. Movement based on CUDA Smoke Demo mixed with frequency calculated. Call to cuda kernels are made through ManagedCuda. Using DirectX 11 on SharpDX. GPU Used is an Nvidia GTX Titan. FPS slow down based only on the amount of alpha blending not on compute FFT or Cuda Smoke simulation.
