Audio Compression ! LPC-based codec model the sound source to achieve good compression. ! Works well for voice. ! Terrible for music. ! What if you can’t model the source? ! Model the limitations of the human ear. ! Not all sounds in the sampled audio can actually be heard. ! Analyze the audio and send only the sounds that can be heard. !

many forms of audio compression techniques offer a range of encoder and decoder complexity, compressed audio quality, and differing amounts of data com-pression. The -law transformation and ADPCM coder are simple approaches with low-complexity, low-compression, and medium audio quality algo-rithms. The MPEG/audio standard is a high-

Although MPEG/audio compression is perfectly suitable for audio-only applications, it is actually one part of a three part compression standard. Combined with the other two parts, video and systems, the MPEG standard addresses the compression of synchronized video and audio at a total bit rate of about 1.5 Megabits/sec.
