I'm a student and I'm going to realize a project with Max/MSP. The idea is a "Virtual DJ" that analyses sound files from a directory. Depending to their velocity (bpm) and the average frequency of the sound signal I want to classify them into an array.

Second I want to analyse the environment in realtime. With the webcam and the microphone I want to find out the loudness and the average color value.

Everytime when a song ends, the new one should be selected considering the information about songs in the array.

I'm an newbie and don't know much about Max/MSP. Just some working with the standard objects.I have some programming experience with Java, PHP and a little bit of C.

I would be really appreciated if one of you could help me out with some good tutorials to start with. And with ideas how to realise these analysing issues:

- How to analyse sound files from one directory? BPM and average Freq. of sound signal.

- How to analyse in real time microphone and webcam?

For the first analysis task, you might want to look at the MEAP

i have a filemaker pro database solution that i made for this (excluding the colors)

i would be very interested in your patch 

there are several beat detectors (based on [bonk~] mostly)

and pitch detectors (based on [fiddle~] mostly)

they only work in real time - not on files

also
think about including overlaps and drops
