Hi Jim,

Hi Peter,
Thanks for the suggestion. My first goal will be to get the sketch to actually work. I'm getting a null pointer exception and a message about the display not existing - which I take it to be tied in with the Displayer class the program is using -  perhaps an incompatibility with Processing 2.

A first pass through the code does not reveal to me an obvious ability to tie time to data.  My understanding is that because the music is being streamed  you don't know precisely what is the moment in time in the audio that is associated with any particular buffer element. 

Too bad I can't just say "hey Minim, give me the data sample that resides at the 1234 millisecond point in time in the audio file."

Best Regards, Jim

FYI,
I think that this will in part further illustrate my problem:
screen at 60  (frames per second)
sound at 44100  (samples per second) (per player.sampleRate())
mp3 is 16849 milliseconds long (per player.length())
audiobuffer is 1024 (minim.loadFile() default)

At the conclusion of the song I have read a total of 130,870 buffer array elements
via for(int i = 0; i < player.bufferSize() - 1; i++)

I commented out a couple statements in the for loop and ran the sketch again.
This time I read 142,134 buffer array elements - 10K more than the 1st time.
More commented-out statements results in 1,050,622 buffer array elements read - a increase by a factor of 7!

So how can I determine at what point in time in the song the nth element of the input buffer represents?


Best Regards, Jim
