The Codec software doesn't have any state interaction between frames at
present, but FreeDV does. FreeDV in some modes steals one of the voicing
bits from the Codec for a data channel, and then reconstructs it through
interpolation. This will not concern you if you aren't using FreeDV.

Does the codec2 instance retain any analysis info between encoding 2
consecutive 20/40ms audio chunks
so that i have to use 2 instances to encode/decode the incoming and
outgoing audiostreams in a voip app?
Does codec2 encode each 20/40ms block completely separate as if it
were the very first chunk of an audio stream?
If yes why :-)
