The text is a somewhat incoherent string of words, but as far as I can tell, the author managed to extract an iPod's bootloader by encoding the raw bitstream in audio and emitting it via the piezo sound generator and then recording and decoding the result on a PC to reconstruct the binary data. Nice. Reminds me of acoustic couplers.
