--
-- # 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 flexibility.
-- 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
--
--
-- **Pro-Tipp** - use the command line with power shell to call DCS-SR-ExternalAudio.exe - it will tell you what is missing.
-- and also the Google Console error, in case you have missed a step in setting up your Google TTS.
-- E.g. `.\DCS-SR-ExternalAudio.exe -t "Text Message" -f 255 -m AM -c 2 -s 2 -z -G "Path_To_You_Google.Json"`
-- Plays a message on 255AM for the blue coalition in-game.
--
-- ## Set Voice
--
-- Use a specific 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
-- For voices there are enumerators in this class to help you out on voice names:
--
-- MSRS.Voices.Microsoft -- e.g. MSRS.Voices.Microsoft.Hedda - the Microsoft enumerator contains all voices known to work with SRS
-- MSRS.Voices.Google -- e.g. MSRS.Voices.Google.Standard.en_AU_Standard_A or MSRS.Voices.Google.Wavenet.de_DE_Wavenet_C - The Google enumerator contains voices for EN, DE, IT, FR and ES.
--
-- ## 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 SRS Volume
--
-- Use @{#MSRS.SetVolume} to define the SRS volume. Defaults to 1.0. Allowed values are between 0.0 and 1.0, from silent to loudest.
--
-- ## Config file for many variables, auto-loaded by Moose
--
-- See @{#MSRS.LoadConfigFile} for details on how to set this up.
--
-- ## Set DCS-gRPC as an alternative to 'DCS-SR-ExternalAudio.exe' for TTS
--
-- Use @{#MSRS.SetDefaultBackendGRPC} to enable [DCS-gRPC](https://github.com/DCS-gRPC/rust-server) as an alternate backend for transmitting text-to-speech over SRS.
-- This can be useful if 'DCS-SR-ExternalAudio.exe' cannot be used in the environment, or to use Azure or AWS clouds for TTS. Note that DCS-gRPC does not (yet?) support
-- all of the features and options available with 'DCS-SR-ExternalAudio.exe'. Of note, only text-to-speech is supported and it it cannot be used to transmit audio files.
--
-- DCS-gRPC must be installed and configured per the [DCS-gRPC documentation](https://github.com/DCS-gRPC/rust-server) and already running via either the 'autostart' mechanism
-- or a Lua call to 'GRPC.load()' prior to use of the alternate DCS-gRPC backend. If a cloud TTS provider is being used, the API key must be set via the 'Config\dcs-grpc.lua'
-- configuration file prior DCS-gRPC being started. DCS-gRPC can be used both with DCS dedicated server and regular DCS installations.
--
-- To use the default local Windows TTS with DCS-gRPC, Windows 2019 Server (or newer) or Windows 10/11 are required. Voices for non-local languages and dialects may need to
-- be explicitly installed.
--
-- To set the MSRS class to use the DCS-gRPC backend for all future instances, call the function `MSRS.SetDefaultBackendGRPC()`.
--
-- **Note** - When using other classes that use MSRS with the alternate DCS-gRPC backend, pass them strings instead of nil values for non-applicable fields with filesystem paths,
-- such as the SRS path or Google credential path. This will help maximize compatibility with other classes that were written for the default backend.
--
-- Basic Play Text-To-Speech example using alternate DCS-gRPC backend (DCS-gRPC not previously started):
--
-- -- Start DCS-gRPC
-- GRPC.load()
-- -- Select the alternate DCS-gRPC backend for new MSRS instances
-- MSRS.SetDefaultBackendGRPC()
-- -- Create a SOUNDTEXT object.
-- local text=SOUNDTEXT:New("All Enemies destroyed")
-- -- MOOSE SRS
-- local msrs=MSRS:New('', 305.0)
-- -- Text-to speech with default voice after 30 seconds.
-- msrs:PlaySoundText(text, 30)
--
-- Basic example of using another class (ATIS) with SRS and the DCS-gRPC backend (DCS-gRPC not previously started):
--
-- -- Start DCS-gRPC
-- GRPC.load()
-- -- Select the alternate DCS-gRPC backend for new MSRS instances
-- MSRS.SetDefaultBackendGRPC()
-- -- Create new ATIS as usual
-- atis=ATIS:New("Nellis", 251, radio.modulation.AM)
-- -- ATIS:SetSRS() expects a string for the SRS path even though it is not needed with DCS-gRPC
-- atis:SetSRS('')
-- -- Start ATIS
-- atis:Start()

-- @param #string Filename File to load, defaults to "Moose_MSRS.lua"
-- @return #boolean success
-- @usage
-- 0) Benefits: Centralize configuration of SRS, keep paths and keys out of the mission source code, making it safer and easier to move missions to/between servers,
-- and also make config easier to use in the code.
-- 1) Create a config file named "Moose_MSRS.lua" at this location "C:\Users\<yourname>\Saved Games\DCS\Config" (or wherever your Saved Games folder resides).
-- 2) The file needs the following structure:
--
-- -- Moose MSRS default Config
-- MSRS_Config = {
-- Path = "C:\\Program Files\\DCS-SimpleRadio-Standalone", -- adjust as needed, note double \\
-- Port = 5002, -- adjust as needed
-- Frequency = {127,243}, -- must be a table, 1..n entries!
-- Modulation = {0,0}, -- must be a table, 1..n entries, one for each frequency!
-- Volume = 1.0, -- 0.0 to 1.0
-- Coalition = 0, -- 0 = Neutral, 1 = Red, 2 = Blue
-- Coordinate = {0,0,0}, -- x,y,altitude - optional, all in meters
-- Culture = "en-GB",
-- Gender = "male",
-- Google = "C:\\Program Files\\DCS-SimpleRadio-Standalone\\yourfilename.json", -- path to google json key file - optional.
-- Label = "MSRS",
-- Voice = "Microsoft Hazel Desktop",
-- Provider = "Microsoft", -- this is the default TTS provider, e.g. "Google" or "Microsoft"
-- -- gRPC (optional)
-- GRPC = { -- see https://github.com/DCS-gRPC/rust-server
-- coalition = "blue", -- blue, red, neutral
-- DefaultProvider = "gcloud", -- win, gcloud, aws, or azure, some of the values below depend on your cloud provider
-- gcloud = {
-- key = "<API Google Key>", -- for gRPC Google API key
-- --secret = "", -- needed for aws
-- --region = "",-- needed for aws
-- defaultVoice = MSRS.Voices.Google.Standard.en_GB_Standard_F,
-- },
-- win = {
-- defaultVoice = "Hazel",
-- },
-- }
-- }
--
-- 3) The config file is automatically loaded when Moose starts. YOu can also load the config into the MSRS raw class manually before you do anything else:
--
-- MSRS.LoadConfigFile() -- Note the "." here
--
-- Optionally, your might want to provide a specific path and filename:
--
-- MSRS.LoadConfigFile(nil,MyPath,MyFilename) -- Note the "." here
--
-- This will populate variables for the MSRS raw class and all instances you create with e.g. `mysrs = MSRS:New()`
-- Optionally you can also load this per **single instance** if so needed, i.e.
--
-- mysrs:LoadConfigFile(Path,Filename)
--
-- 4) Use the config in your code like so, variable names are basically the same as in the config file, but all lower case, examples:
--
-- -- Needed once only
-- MESSAGE.SetMSRS(MSRS.path,nil,MSRS.google,243,radio.modulation.AM,nil,nil,
-- MSRS.Voices.Google.Standard.de_DE_Standard_B,coalition.side.BLUE)
--
-- -- later on in your code
--
-- MESSAGE:New("Test message!",15,"SPAWN"):ToSRS(243,radio.modulation.AM,nil,nil,MSRS.Voices.Google.Standard.fr_FR_Standard_C)
--
-- -- Create new ATIS as usual
-- atis=ATIS:New(AIRBASE.Caucasus.Batumi, 123, radio.modulation.AM)
-- atis:SetSRS(nil,nil,nil,MSRS.Voices.Google.Standard.en_US_Standard_H)
-- --Start ATIS
