Digital voice with Codec2 or Opus codec was implemented just for fun.
It is not intended to replace or compete with FreeDV. It cannot do that either because the latency times are far too long for QSO operation.
Due to its high speed, HS-Modem is primarily intended for higher bit rates, which are currently not supported by Codec-2. If there will be a Codec-2 with bit rates in the range 4000 to 6000 in the future, it makes sense to operate it in HS modem, and then it will be installed immediately.
In the meantime, FreeDV is the ideal program for DV operation.
