Good. One compatibility thing that springs to mind for the future: if the header needs to be extended, try to extend it in multiples of LCM() of all block sizes. lcm(4,6,7,8) = 168. That way, while there may be garbage for the first couple of frames, the bitstream is properly framed after that. > A road map of what is currently placed for the entire FreeDV project > (which includes Codec 2) is here: > > https://freedv.org/2023/11/30/ardc-grant-project-plan/ > > Do you have any way of measuring how many people are using the Codec > 2 > option in FFmpeg? I do not, but I was contacted by someone who has been encoding audiobooks using it. codec2 + zip makes for even smaller files There may also be interest in the open telephony sphere. > We have been looking into the use of the freedv-gui application > (which > uses libcodec2) in various repos and found no evidence of the > packaged > versions of freedv-gui actually being used.

Probably because DSP is harder :) /Tomas _______________________________________________ Freetel-codec2 mailing list Freetel-codec2@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freetel-codec2
