END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

http://bit.ly/1mHZ7Mb < This was my old experiment (2011-12? I used to call it boxsound) using FFT to analyse the frequency of an audio file inside boxplorer (open boxplorer, then first open an audio file and then select a .cfg file), it works only on Windows, it was used to create this video, then abandoned http://bit.ly/1mkHeT5
uniform float fft_out can be used to read FFT from audio file (see fragment.glsl file).
