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. !
