Hi all,


I m working in a student project(Voip). i want to know all the details of how a-law/mu-law compression techniques works??(at the bit level). it will be better if you provide an example which will make the idea clear.


waiting for replies.........


Thanks in advance Srikanta Agrawala



i also write assignments for a modest fee, for students with rich parents who want to get a qualification without learning anything

There's an article (and published implementation for an AVR based VOIP phone) in the latest Circuit Cellar.
