The 3GPP Enhanced aacPlus general audio codec offers monophonic and stereophonic coding. For stereophonic coding two stereo modes are used: parametric stereo for low bitrates and M/S stereo for high bitrates. The codec is based on the MPEG-4 Audio ISO standard. The cited ISO standards define several profiles and levels of which not all
