Raw vs. Compressed Audio

It is important to consider that audio being transported via RTP may be compressed. To successfully embed message data into a cover-medium, it is generally required that it is performed against the raw data so as to properly identify and utilize the cover-medium's redundant bits. As such, identification of compressed cover-medium, decompression, modification of the raw data, and then re-compression may be required.
