Hi Al,
So you need both the codec2 data and the audio?
In that case I would use the freedv_rawdatarx function to get the codec2
data.
The audio data can be retrieved by calling codec2_decode() with it, then
you have both.
If you use the freedv_rawdatarx() function the text callback functions
will still be called in the same manner as if you had used freedv_rx()
so that should not be a problem.
73,
