If you love audio and you love visuals as much as I do. Then this is something that you are going to love too. Wouldn’t it be great to get the two working in unison in real time and automatically?
Audio and Visuals will make or break the success of a video. One compliments the other and the greater the stage, the more crucial the two become.
With that in mind, let me introduce to you a unique and exciting project I’m currently on
Deeper Explanation:
An FFT of 512 samples is taken using BlackmanHarris. The range of frequencies in most music is 22050hz. So 22050hz / 512 samples works out at 43hz per sample. Calculating the average of a “Band of samples” is done by Looping through the amount of bands to create i.e. 64. Then loop through the amount of samples
if count = 0, 2 to the power of 0 = 1, 1 * 2 = 2. So would be in the first frequency band. 0-2 = 86hz.
On the last loop you would need to add the 2 back on to loop through the full 512 samples.
Calculate the average by adding the samples multiplied by the count + 1. Add 1 to the count and at the end of the of the band loop then divide the average by the count.
These frequency bands produce a useable range of values which can be used for endless possibilities.
