About

Hi, I'm David Rowe.

I'm developing Codec 2, the open source speech codec that is outperforming closed source speech codecs at very low bit rates. I've combined Codec 2 with advanced modems and forward error correction to produce FreeDV - open source software for digital voice over HF radio.  FreeDV already works better than Single Sideband (SSB) over tough HF radio channels (Listen to SSB-FreeDV-SSB example)

You can help me make Codec 2 and FreeDV even better.
