Speex: a free codec for free speech


What We're Doing

We're implementing and debugging new features such as a denoiser, echo canceller, and a jitter buffer. In addition, we're testing out a new VAD.

How You Can Help


  • writing a plugin for your favorite audio player
  • helping make Speex a more widely recognized standard; work is already underway to make Speex an IETF-blessed standard, but work still remains in that arena. If you know of an organization that standardizes (on) audio compression codecs, consider proposing Speex as an option.
  • Test and push the limits of the software
