dxw00d:
If I understand it correctly, your algorithm analyses amplitude over time, and assign different amplitudes to your column array. An FFT algorithm, (again, as I understand it), effectively breaks down the incoming signal into different frequency bands (for example, bass frequencies, mid-range frequencies and high-range frequencies) and then analyses the amplitude of each band, which would then be assigned to the columns.
Okay, do you mean to say that for example from audio output comes 225 and it somehow breaks it into components? Is that really possible? Well if it is like that then it is really my bad:D Thank you for sharing with me. And yes if u want to visualize your audio, my method seems to be pretty nice.
It is laggy(phone camera), but at the end of it you can see the visualization. I have only 5 columns working, since it is what is needed for my project.
UPDATE: If i understand correctly breking into frequencies means breaking the complex sound wave into simple sin and cos waves?
