There are quite a few VoIP codecs. A person who does not know much about the differences between them, the strengths and weaknesses of each, is difficult to choose. Prompt fast modern non-licensed codecs (maybe offer a few to choose from).

  • Then close the question, most likely on Software Recommendations try to ask. Thank. - Sasha Chernykh
  • For what purposes do you need a codec (conferences, broadcasts, calls between two subscribers)? The question is very general. Is it possible to clarify the question, for example, “Which codec wideband codec for audio can be used for video broadcasting to 50 people, if the speed of the incoming channel of clients is <2 Mbit”? - Tihon
  • Calls between two subscribers - D .Stark

If you do not understand and do not delve into the details, choose what is by default in your telephony (probably it will be G.729 and G.711).

You have to decide what you want. Good sound or good compression for the ability to speak such a 3g?

If anything, opus is actively sweeping around the world - in almost all IM it. But unfortunately, sip has not yet caught up on innovations.

  • You have to decide for yourself what you need - a modern unlicensed codec that minimally loads the processor and provides high-quality sound (compression if only lossless). - D .Stark
  • flac lossless compression - but there is no such thing in telephony. Watch opus - almost all im work on it. good quality. - hardworm

    G.729 requires license fees (not to be confused with G.729A). - Tihon
  • But after all, OPUS is bad, since it does not support 44 kilohertz in principle. Then the boys, of course, came to their senses and gash ... A separate codec for 44 kilohertz. And now there are 2 codecs OPUS. One does not even recommend to use. - bukkojot

Hello Friend! I have the perfect option for you:

MP3

Benefits:

  • hardware decoder in almost every chip, in every coffee maker
  • high sound quality, especially at 320 kilobits
  • commercial quality of both encoders and decoders
  • a large selection of ready-made libraries for all possible platforms
  • all patents have expired and you can safely use it in your projects

Over the years of the MP3, the community has written quite a few good decisions. You just have to take the fruits of other people's work and just link them to your project! And no one needs to pay!

  • MP3 is not a VoIP codec ... - D .Stark
  • Who cares? - bukkojot
