Advanced Combat Radio Environment 2 (ACRE2)


Welcome to the ACRE2 Stable release! For those who are not familiar with ACRE from Arma 2 or the ACRE2 Beta which has been released for almost a year, ACRE is a full fledged communications suite for Arma, allowing realistic radio and voice communications through Teamspeak 3. The original ACRE released in the Summer of 2010 set the bar for communications in the Arma series and allowed what was once the tedious and long task of organizing Teamspeak or Ventrilo channels, with multiple whisper lists and no direct communications between groups, to be reduced to a natural implementation in a single Teamspeak channel. All players are able to speak with each other directly or use in game configurable radios to communicate at longer distances providing unparalleled immersion in the Arma series.

ACRE2 takes what ACRE1 pioneered to a whole new level. With increased performance and stability ACRE2 provides and even more immersive communications experience for the Arma user. Direct voice communications has had a complete overhaul and introduced new features such as occlusion from the environment, including vehicles and buildings, as well as multi-channel audio, allowing voices to be heard from multiple sources. A new virtual language feature in the Babel System allows mission makers to designate "languages" to certain players, making those that do not speak the same language indecipherable. This presents a multitude of gaming scenarios including player translators (Babel allows multiple languages per-person) and enemy communications that are unable to be understood.

The core feature of ACRE has always been radios though, and that has undergone major improvements in ACRE2 as well. A new, extremely powerful and modular distributed data system allows for a whole manner of new features to be simulated in a robust and reliable way, and powers the most realistic real time radio simulation released in either the civilian or military market. The new data system is designed to support large numbers of radios, in a JIP compatible and persistent world setup, as well as allowing for the future implementation of highly advanced features such as data event logging and radio replay ability. While the public beta only implements two functional radios at the moment the robust and well documented framework allows for rapid prototyping and easy implementation of new radio systems by ACRE as well as the community at large. The entire system is implemented in a way to maximize commonality with current Arma modding practices, going so far to even allow individual sounds of the radios to be modded by the community or any other feature.

Current TS3 Support:

A short list of the features in ACRE2:
Accurate simulations of AN/PRC-343, AN/PRC-77, AN/PRC-148, AN/PRC-117F, AN/PRC-152.
Real time voice occlusion for world objects, including buildings.
Babel language system that allows you to implement virtual languages on other players.
Multi-channel audio, allowing people on the radio to be heard locally as well.
Radios with external speakers.
Highly detailed radio signal simulation.
Increased performance and stability.
A highly customizable and documented framework for the creation of radios.
A highly customizable and documented framework for implementing different game modes (persistent world, replays, logging, external data storage, external radio control).
Customizable sound configs that allow traditional patching of sounds played in ACRE via Arma addons.
Customizable radio presets, allowing groups to define radio presets in additional addons for mission makers to take advantage of (also see the F3 framework).
Enhanced and easily configurable vehicle sound occlusion and intercoms.

Download from the above link and extract the zip file to your hard drive.
Open the extracted folder and open the Teamspeak/plugins folder.
Copy the correct version of the plugin dll for your Teamspeak installation.
Navigate to your Teamspeak installation and open the plugins folder.
Paste the plugin into that folder, overwriting any current ACRE2 plugin.
Return to the extracted folder and go to the Game folder.
Copy the @ACRE2 folder.
Navigate to your Arma 3 installation folder.
Delete any current @ACRE2 folder and then paste in the @ACRE2 folder you copied from the extracted zip.
Create a new shortcut or edit an existing one, and add @ACRE2 and @CBA_A3 to the -mod parameter, for a longer explanation see this tutorial:
Launch Teamspeak 3 and enable the ACRE2 plugin in the Settings > Plugins window.
Launch Arma 3 from the shortcut you created.

Mission Maker API:

The wiki is still a work in progress and more information and tutorials will be added in the near future.

Known issues:
If you encounter a bug not found in this list please report them at the ACRE2 issue tracker here:

Limitation: No retransmission currently. Retrans is currently not implemented, it is a feature that will be available shortly though as it is something I consider critical.
Limitation: When speaking on a radio and there is a radio nearby with its external speaker on you can not hear your own voice. This will be fixed in the future.
Limitation: On JIP or disconnect, the ArmA3 engine occasionally stutters for less than a second as data synchronizes with the new player. This is being slowly fixed by BI with their new network engine changes recently in 1.44
Limitation: Some maps cause a modulation for voices on direct speaking when running quickly through buildings. Alternatives to correct this are being investigated

If your dedicated server restricts the types of files clients can load, please follow this advice on how to prevent issues with ACRE2 where clients can not use their PTT key or hear radio squawks:

The following is NOT a issue, and is a FEATURE in ACRE2: When you are in game and ACRE is connected you will NOT be able to hear people that are not in the game as well. This is meant as a failsafe to any issues where someone might be having connectivity issues with ACRE and it is designed to minimize and reduce situations that can reduce immersion.

The following is NOT a issue, and is a FEATURE in ACRE2: ACRE simulates half-duplex radio communications as the real radios in real life do, and this may take new users a while to get used to. Half-duplex communications means only a single person can transmit at the same time, on the same radio net. The API provides the ability for communities to switch to full duplex if they require it.
