audio compression algorithms .Overview of standards-First i need a general reference over multimedia [login to view URL] of the audio history from the beginning till now. What needs served at a time and what kind of objective and subjective improvement occurred,what stood out on dissemination .reference of the psychoacoustic models briefly and the use of it concerning the subjective [login to view URL] will be also a small reference to why traditional compression methods such lzw and huffman and other general purpose lossless compression algorithms ,are not playing well over audio signals and therefore special algorithms had emerged in this area. In the comparative study of popular algorithms, reference will be made to coding algorithms that are widely used both lossy and lossless [login to view URL] the pros and cons will be mentioned separately for each audio [login to view URL] will be reference to the existence of closed and open standards along with pros and cons of these and their ecosystems. Finally there will be reference to future trends and make references like for example opus and other respective trends.
