try this code below :

Code:

f = createForm()

btn1 = createButton(f) -- button volume down
btn1.top = 10
btn1.left = 10
btn1.width = 70
btn1.height = 50
btn1.caption = 'Vol Down'

btn2 = createButton(f) -- button volume up
btn2.top = 10
btn2.left = btn1.left + btn1.width + 10
btn2.width = 70
btn2.height = 50
btn2.caption = 'Vol Up'

btn3 = createButton(f) -- button volume down
btn3.top = 70
btn3.left = 10
btn3.width = 150
btn3.height = 50
btn3.caption = 'Master Volume'

function volup()
doKeyPress(0xAF)
end

function voldn()
doKeyPress(0xAE)
end

function mstrvol()
shellExecute("C:\\Windows\\System32\\SndVol.exe")
end

--function rdmute()
-- doKeyPress(0xAD)
--end

--function rdsnd()
-- doKeyPress(0xAD)
--end

btn1.onClick = voldn
btn2.onClick = volup
btn3.onClick = mstrvol
f.show()

To test :

- open and play a song / game (use your default song player)
- execute script above and test to increase/decrease system volume

Unlucky i am not find how to output volume indicator yet, as a number

Some questions :

1. If open a game / song or movie using Windows Media Player or other media player, how to control volume by use that script ?

2. How to ise that script to control volume only, not include play, pause, stop functions ?

Your explanation will be hep me a lot...

This is the question that I gave the code:

Every search was just on how to play a sound in cheat engine.

That's the question of your code:

Probably your code will solve the problem.

I'm sorry, @Corroder, I've noticed now that you mean System voice. Wink

I am not misunderstand what you want. My script above is to show how to control (or set) master volume using keypress event. But as I said, I don't know how to GET sound volume level and print out it to console or others.

I am not see something to GET sound volume level from a media in Cheat Engine lua yet. Something call as Volume Enumerations, but if you must to do it using Lua, then check these :

https://awesomewm.org/awesome-www-backup-old/wiki/Volume_control_and_display.html
https://gist.github.com/rdp/8363580

or use tool :

I only want to monitor the sound being produced by the game. So the game is playing music and sound effects and being output at a certain decibel level. Then when the decibel jumps up a bit after this certain sound fx get played. Then it does what I tell it too in the script. I just don't know if this is possible using LUA.

First, in order to use these sounds in Lua
you need to search and encode the change.
Sample:
A Flash Decompiler program, game related
monitors all media and can give their execution codes.
and you can work with these codes in Lua.

So; A Piano Tiles game like hacking voice tones ..

Lua/CE does not have a way to check the current amount of sound coming out of a speaker/from a process. Not sure if the windows API does either but maybe... In theory pretty much anything is possible if you have enough knowledge, unfortunately I've never worked with sound enough to know.

Look into doing things via Powershell instead. From Lua you can launch a PowerShell instance and execute a lot more in-depth things. For example: https://stackoverflow.com/a/31751275 _________________ - Retired.
