Codec2 Open Source Vocoder Project

David Rowe, VK5DGR, is working on Codec2, an open source low rate speech codec that is intended to replace the proprietary AMBE vocoder in D-STAR.  Bruce Perens, K6BP, discusses the Codec2 project here, and further information from VK5DGR is here.

If you missed it, I discussed the issues with proprietary technology and D-STAR here, here, and here.

If you believe open source technologies are crucial to amateur radio, please donate to the Codec 2 project.  Paypal donations are accepted.
