cool idea

[TheBigBasicQ]

Well if you are really interested in doing this then you will have to take some efforts and calculus aint so bad =P

Well, first of all: HELLO!!! Look, since my begining in computer programming i've loved demos. The idea you exposed is just like a demo. The graphical part could be awesome to see. It will require lots of calculations to simulate the physics, but i think it could be done in QB.

Where you will have to effort is on the sound part. Sound can be played on second plane, using a library, without consuming much processor time (trough DMA). But, to detect beats, bass, treble, etc, you, as na_th_an said, will need spectral information about the music you are playing. Doing so is not difficult but expensive. A windowed FFT may be applied to the sound played, in real time. There is no need to apply any low nor high pass filter since you are not filtering but detecting frequencies. I think this part can't be done with qb due to speed factor, you will need assembly for it.

Anyway, the graphic part without the bass peak detection is cool enough. I'm sure my experienced and good-friend na_th_an would be able to code it in QB . Maybe, when I have some free time could try too.

Regards for all the crew!!
