Question

I want to write a VoIP program using C#, in which I want to encode/decode outgoing and incoming streams myself. I will appreciate, if you can tell me, what library I can use for it and where can I can find that library.

Answer 1

You could try NSpeex for a fully managed codec implementation.

NAudio will let you use any ACM codecs on your system, so you can use G.711 a-law and mu-law, ADPCM, GSM 6.10, G.723.1, TrueSpeech or WMA, which come with Windows as standard. It also has managed a-law and mu-law encode/decode.
