# I set myself a challenge to code a piece using only white noise.
# White noise contains equal amounts of energy at every (audible) frequency.

# It sounds like this:
#synth :noise

# Not very musical.

# But... it contains every frequency, so every possible sound or piece of music
# is hidden in there somewhere... you just have to filter out the parts you don't want.

# I will use no source of sound other than "synth :noise", passing it through different
# filters and effects to try to create something that sounds a bit less like noise...

# To run this, progressively comment out the "stop"s in each live_loop, hitting run each time...

Hi dude, It's really a pleasure for me to hear this sound! May I know how you learn sonic pi？

@ruan1998 there's a tutorial built into Sonic Pi that's really good, I'd recommend starting with that. And then you could use the forum for any more specific queries.
