Hi!
I´m a processing newbie. I want to make a file where a picture changes colors depending on the sound i make by myself (whistle for example). But I have no idea where to start... So please help me.
Thanks

Also, to get realtime audio, aside from adjusting your system audio preferences (recording levels especially!), you want a "line in" reading.

See in the examples that come with Processing:
File (menu) > Examples > Libraries > Minim (Sound) > GetLineIn

Also look at the docs for Minim, especially AudioInput

One more question, sry

I have a programm where a line rotates round the courser. Additionally I have selfmade shapes wich i can activate by pushing a key but they don´t work.Their names are "02.svg"-"06.svg"(illustrator)
And the line is sensible preferring to the sound. A loud noise will make the line kick out. But additionally i want to make a random color for every loud noise like clap e.g. Can someone help me and take a look at my code?
Would help me a lot.
Thx=)

tried it but it doesn´t work.... there is no difference....

At my Mac it works fine too. And it was my intention that the screen fills up after i pushed the mouse button. It doesn´t matter how long it needs to fill up the screen because this is a intendet setting.... if i set one number a little bit smaller, the screen needs longer to fill up....

My Problem is that i don´t know how to make the color of the line changing randomly after a noise like clap e. g..... I tried it with:

while, with the in.mix.level() etc. but i don´t know how to make this.....
