I want to draw a single line on canvas, this line must have a form(waveform) which depends on audio data. How to achieve this in J2ME?

well I guess this should be divided into several parts...
first of all the audio-capture...
then the transformation (fourier maybe?) from the audio to a pattern
then draw this pattern on a canvas...

There is no available API or something for that, so I guess you could as well start out with your own implementation...
