DV

When I get around to is, this page will house my digital voice transmission work. At the moment, this is all just a theory, based on the work of various others. Nothing concrete, but revolving around:

• Codec 2 at 1400 bits/s - A very low bandwidth audio codec using LSP methods.

The idea would be to sample microphone audio. Convert it to a digital signal. Compress it, possibly using the above Codec 2 codec. Modulate it at base-band. Feed it into an amateur radio transmitter for transmission where desired.

I would also like, as suggested by Dave to include video frames within the spare data slots. This way, we would get some low resolution low frame-rate images - could be nice.

Check back here soon; I keep on thinking about this - something must happen!
