I'm having these two sound files and now I'm looking for some different methods for comparing em', to find out how similar they are.

Anyone know if there are any easy methods available for that kind of operation in max/msp?

transient analysis/ beat tracking would give clues as to tempo, 

Pitch tracking might reveal issues with pitch/harmony/keys,

but if the sounds are polyphonic this is *very* difficult.

I think you need to ask the question my reply started with ...

and when you can clearly state that, go looking for analysis tools 

There was a recent Computer Music Journal issue (v28:3 Fall2004 )

What would a query to find a sound :"like" another sound have to have?

There are many approaches, and they all differ a little in how they 

hmm...this is not as simple as it seems:
Similar in what ways?

some ideas in the thread called Scrambled HackZ ideas, not long ago...

Ohh I see. Never really thought of similarity in such a complex way. The similarity I look for, would prolly just be in something like frequenzy, amplitude or pitch.

I'll recommend to read "Goedel, Escher, Bach" from Douglas R. 

Hofstadter, which shows how difficult it is to compare fonts, which 

seems easy for humans. To compare sounds seems even difficult for humans...

But there is hope, we had the thread about the scrambled hackz idea..., 

which needs some kind of comparison between sounds. You'd need to 

analyze the sound in different ways, maybe teach a neural net...

Anyway let us know with what you come up. It would make up a great
