its simple because files is not encrypted
here example on python 2.x
Code:
import os
import sys
name = raw_input('Inter filename: ')
dir = (name.split('/')[-1]).split('.')[-2]
data = open(name,'rb').read()
data = data.split('OggS',1)[1]
data = 'OggS' + data
data = data.split('OggS\x00\x02')
if not os.path.isdir(dir): os.mkdir(dir)
for i in xrange(len(data)):
print data[i][:3].encode('hex'),' - ',data[i][-3:].encode('hex')
open('%s/track_%s.ogg'%(dir,i),'wb').write('OggS\x00\x02' + data[i])
tmp = raw_input('Press ENTER to quit...')
quit()
after this you have subdir with files
