AphexTwining: Image to sound
Yes, we can use povray to build sounds too. Here are some examples, checked in baudline.
Scene, example sound.
Simple picture to sound converter.
This script is not the fastest one: it doesn't use inverse FFT to build the sound,
but the sounds computed are better than using inverse FFT.
LEDs
Video, scene.
Simulation of a stereo LED panel showing audio spectrum.
LED colors change each 30 seconds to show different possible color sets.
Video is HD 720p.
Scene.
Second version of a LED using emitting medias instead of light_source.
The LED macro has 3 input parameters: light intensity, colour and
a on/off switch.
Scene.
A LED panel showing an audio spectrum and the volume level, in dB (decibels).
The panel has input parameters: audio datas, sample rate,
min and max frequencies to show, number of frequencies,
LED colors and a on/off switch.
FFT: Fast Fourier Transform
Video, scene.
This is an over 8000 images 16:9-wide PAL video.
It took about 1 month to be rendered by 2 PCs.
Scene.
This is a portage of a very old BASIC-Apple II source to Povray.
Normal and inverse FFT macros.
Audio datas must be in a array containing vectors
made of 2 values: <left, right>,
or <value, 0> if used with mono signals.
I deliberately chose one of the most funny pictures I have : my haircut is not really like this. ;)
