Hey amigos! I want to share this simple electronic tune which I made for my 12 years old
son, to teach him about the freq spectrum.
It's like the Aphex Twin (equation?)
song, using the scrolling spectrogram you can see some drawings (basic ones, but I am not
good at drawing anyway)
You have to adjust your freq scale so it shows more of the middle range, look at the pic
when going to the link to see it best, and have fun!
