Codec2 V0.1 Alpha Released

I have just released V0.1 of the Codec2 low bit rate open source speech codec. Almost 1 year to the day since the project started with this post. Speech samples and lots of other new information on the Codec2 page.

I was convinced by many to release early with the current algorithm. After listening to some early MELP 2400 bit/s samples I realised we were already in the ball bark with speech quality. A V0.1 release gives people a chance to try out Codec2 while I work on the algorithm quality and bit rate in parallel.

Codec2 currently runs at 2550 bit/s and delivers fair speech quality. It runs 10 times faster than real time on a modest Linux laptop and is usable today for digital radio or VOIP experimentation.
