I am working on a sketch to visualize a short .mp3 file, using minim's "fft" and "beat detecter" functions.

Currently the visual output varies every time I am running the sketch (there are no "random" elements in the program).

I need the data extracted from the audio to be exactly the same each time. The problem may reside in the fact that Processing has to both read/play AND visualize the data in real time. Perhaps, allowing the software to collect the data and THEN visualize it would solve my problem (I don't need this to be live - just get a visual output).

Is there a way to do that with minim?

Any insight would be much appreciated!

thanks!
