The MSRS Concept
This class allows to broadcast sound files or text via Simple Radio Standalone (SRS).
Prerequisites
This script needs SRS version >= 1.9.6.
Play Sound Files
local soundfile=SOUNDFILE:New("My Soundfile.ogg", "D:\\Sounds For DCS")
local msrs=MSRS:New("C:\\Path To SRS", 251, radio.modulation.AM)
msrs:PlaySoundFile(soundfile)
Play Text-To-Speech
Basic example:
-- Create a SOUNDTEXT object.
local text=SOUNDTEXT:New("All Enemies destroyed")
-- MOOSE SRS
local msrs=MSRS:New("D:\\DCS\\_SRS\\", 305, radio.modulation.AM)
-- Text-to speech with default voice after 2 seconds.
msrs:PlaySoundText(text, 2)
Set Gender
Use a specific gender with the MSRS.SetGender function, e.g. SetGender("male") or :SetGender("female").
Set Culture
Use a specific "culture" with the MSRS.SetCulture function, e.g. :SetCulture("en-US") or :SetCulture("de-DE").
Set Google
Use Google's text-to-speech engine with the MSRS.SetGoogle function, e.g. ':SetGoogle()'. By enabling this it also allows you to utilize SSML in your text for added flexibilty. For more information on setting up a cloud account, visit: https://cloud.google.com/text-to-speech Google's supported SSML reference: https://cloud.google.com/text-to-speech/docs/ssml
Set Voice
Use a specifc voice with the MSRS.SetVoice function, e.g, :SetVoice("Microsoft Hedda Desktop").
Note that this must be installed on your windows system.
If enabling SetGoogle(), you can use voices provided by Google
Google's supported voices: https://cloud.google.com/text-to-speech/docs/voices
Set Coordinate
Use MSRS.SetCoordinate to define the origin from where the transmission is broadcasted.
Set SRS Port
Use MSRS.SetPort to define the SRS port. Defaults to 5002.

Set trace off.
Set trace on.
Set trace on or off Note that when trace is off, no BASE.Debug statement is performed, increasing performance! When Moose is loaded statically, (as one file), tracing is switched off by default.
So tracing must be switched on manually in your mission if you are using Moose statically. When moose is loading dynamically (for moose class development), tracing is switched on by default.
