A Tutorial on MPEG/Audio Compression - MIT Media …
https://web.media.mit.edu/~tristan/Classes/MAS.945/Papers/Technical/pan96tutorial.pdf
This tutorial covers the theory behind MPEG/audio compression. It is written for people with a modest background in digital signal processing and does not assume prior experience in audio compression or psychoacoustics. Here the goal is to give a broad, preliminary understanding of MPEG/audio compression; many details have been omitted.

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. !

Newer audio compression technologies MPEG-1 Layer-3 has been defined in 1991. Since then, research on perceptual audio coding has progressed and codecs with better compression efficiency became avail-able. Of these, MPEG-2 Advanced Audio Coding (AAC) was developed as the successor for MPEG-1 Audio. Other, proprietary audio compression systems ...
