Audio for VATSIM will be Released October 14


Hello Everyone,

As you may be aware, Audio for VATSIM, the new VATSIM Codec, will be released on October 14, 2019. It’s important that you update your clients in order to continue transmitting on voice. This is required for everyone and you won’t have the option to stay with the old voice codec. Everyone will have to update their clients before then. You can follow the instructions on how to do this by going here:

Below you will find more specifics on how this is going to work but you can also find all the information you need here:

Thank You,

Ernesto Martinez

 What is Audio for VATSIM?

Audio for VATSIM is an innovative new technology for our voice communication which features:

  • State of the art voice quality – a brand new Opus-based voice codec with realistic distortion, white noise, VHF and HF simulation
  • Reduced delay – up to 80% reduction in latency, making busy frequencies more realistic and manageable
  • Range simulation – transceivers set up as per real ATC positions, with signal strength dependent on distance and altitude
  • Customisable technology – this upgrade paves the way for future amazing development by the community.

This is the biggest technical change for the VATSIM community in many years, and is being rolled out across all pilot and ATC clients. In order to implement this change, we must do two things that have never been done before on the network. First, we must take the entire network offline for maintenance for a short period. Secondly, after the downtime, all VATSIM members will need to have updated their ATC and pilot clients to be compatible with the new infrastructure.


How will the launch work?


At 2000z on Sunday 13th October 2019, all VATSIM servers will be taken offline to begin the migration to our new infrastructure. VATSIM users should ensure that their flights and ATC sessions have concluded by this time. During this period, all other VATSIM services may also be subject to some downtime.


The network will remain offline for a period of 24 hours, although a limited number of connections are likely to be allowed before this time whilst we embed the new servers. To be safe, our members should not plan any flights or ATC sessions prior to 2000z on Monday 14th October. If the downtime needs to be extended beyond this time for any reason, we will announce this as quickly as possible.
