VATSIM have revealed an all-new voice system is currently undergoing beta testing.
The new system brings a complete ultra-low latency, crisp, clear VHF simulation to VATSIM. Features include realistic range and static effects based on line-of-sight calculations, as well as realistic 'blocking' when two or more stations transmit simultaneously based on their proximity to receiving stations.
The new codec will work with all currently available pilot and ATC clients and is currently undergoing closed beta testing.
