Hello Liviu, Once you encoded the wave into MP3, the originality is lost forever. The first wave you'll get will have exactly the same quality of the MP3 of "CBR (-b256 -ms -h)" and the second wave will have exactly the same quality of "VBR (-V1 -b128 -mj -q1)". Think about it for some time, and

Hi Robert, This just seems like a lot of work for no real gain since all 4 libraries are samll and closely related. To build LAME we would need a ./configure setup which builds 4 different libraries. so I guess I just dont see any reason to seperate them. Special applications, like embeded en
