q2. is there any way to change the image of a button?

tks for helping

What do you mean by soundvisual?

For image of a button, are you using the button plugin? If so, see https://www.scirra.com/manual/111/button for possibility of using CSS on the button. However, you can also use Sprite to show the image of a button instead and have "click"/"touch" event on the Sprite to make the Sprite a "button" too.

Hello, tks for your help

And here is the Audio Visual aka Audio Spectrum i mention before.

When a pitch(dk is that the correct word) of a song go high, the bar will go up, when the pitch go low,the bar fall down.

Pretty Hard for a beginner like me, but i belive that C2 can do this thing,i guess

~Knayter form DTBG Studio~

Yes, check the Examples that came with C2. Look for the file Audio analyser.capx in the Example folder.
