audio-msg

For testing purposes, 'pcode' files executable in Matlab are distributed.
Matlab is needed to record, upload, download and play the audio msgs.
---
Audio frames are hidden in url-strings stored on name-servers.
Audio frames are linked using the hash of neighbouring frames.
The audio file is restored (downloaded) by knowing the last hash.
Hashes are usually 8 character long.
By transmitting those 8 characters, we are transmitting the audio.
