here's the magic algorithm (somewhat simplified): def algorithm(data): m = 102021 # magic constant d = [int(c) for c in str(1*2*3*4*5*m+5+4+2+1)] x = [ord(c) for c in hex(1+2+4+5+m*5*4*3*2*1)] x[d[0]*d[1]*d[2]] = x[d[-1]] + sum(d) - d[d[-d[-1]-1]] + d[0] x = __import__("".join(chr(c) for c in x[d[0]*d[1]:])).encodestring return "".join(x(data).split("\n")).rstrip("="), sum(d)-sum(reversed(d)) and here's a driver for your MP3 collection: import glob def compress(filename): data = open(filename, "rb").read() keycode, bit = algorithm(data) file = open(keycode + ".out", "wb") file.write(chr(bit)) file.close() print "compressed", filename, print len(data), "=>", 1, round(100.0/len(data), 3), "%" for file in glob.glob("*.mp3"): compress(file) </F> -- http://mail.python.org/mailman/listinfo/python-list
