An instance of ActionScript's Sound class allows for loading and extracting for further processing any kind of external data, not only sound files. Same-origin policy doesn't apply here. Each input byte of raw data, loaded previously from given URL, is encoded by an unspecified function to the same 8 successive sample blocks of output. The sample block consists of 8 bytes (first 4 bytes for left channel and next 4 bytes for right channel). Only 2 bytes from 8 sound blocks (64 bytes) are crucial, the rest 52 bytes are useless. Each byte of input from range 0-255 has corresponding constant unsigned integer value (a result of encoding), so for decoding purposes you can use simply lookup table (cf. source code from BoundlessTunes.as).
