The project is arranged into five C# files. One is Program.cs, which is not really important until later, and even then, it isn t so terribly important. The other four are static classes, MuLawEncoder, MuLawDecoder, ALawEncoder, and ALawDecoder, which all do exactly as their names imply.



The static constructors do all of the real work, and store the results in a table. When the Encode or Decode methods are called, they look in the table. At the cost of only a little memory (64 KB per encoder, 0.5KB per decoder), it is definitely worth it.
