Audio file with Processing

Hi everybody!! I have some questions: If i want to transfer an audio file in the Arduino through the Processing, how can i do?? and then, the memory of the arduino is very small for an audio file... Thanks a lot for the answers...!!!

It all really depends on what you want to do, and how fast, or with how much allowable latency.

I explain you: The processing has to transfer an audio file to the arduino, the arduino, when recive this file, has to execute a FFT calculate and then transfer the results to the processing for an audio spectrum....(in real time) I know that the processing can do the FFT with the audio libraries, but i have to do this project... Now, i hope that' s more clear??...
