OBS Voicemeeter Integration

An application to integrate OBS and Voicemeeter using your voice, keyboard shortcuts and more!


Okay, so let me get this straight. This is not a plugin. It's not even an application with a proper UI. Then why bother? Well, don't ask me. You're the one who's here!

OBS Voicemeeter Integration Server (for lack of a better name) is an application that allows you to synchronize between OBS and Voicemeeter (). I'm a huge fan of both the applications. In case you didn't know, OBS Studio let's you live stream pretty much anything, while Voicemeeter is like a virtual audio mixer. OBS does have audio provisions, but if you're already a Voicemeeter user, you'll find it annoying to change all your configuration. Voicemeeter doesn't let you use any audio devices while it's open, so you have to close it and spend a good half-an-hour each time you want to stream. And that's exactly why I made this application!

Prerequisites

Well, you need to have OBS installed (obviously!) and you also need to have Voicemeeter installed. Like I mentioned before, this applciation will ONLY WORK on Windows. Also, you need to have the OBS Websocket plugin installed. Please set the port to the default of 4444 and please don't set any password.

Using it out of the box

Download and install the EXE.

NOTE: Voicemeeter is only there for Windows, so naturally, this application is there only for Windows.

Run the EXE file. It will probably give you an error and shut down. You need to open OBS, genius! You need to open Voicemeeter too.

After you open the application, wait a few seconds. Then edit the file C:\Users\{your username}\AppData\Roaming\obs-voicemeeter-integration\server-config.json with some JSON in the following format. Make sure that all your scene names are in small letters and that they don't contain any characters such as hyphen, period, brackets, etc. Also, make sure that there is no scene named "config". Again, if you're building the app yourself, you can just run update-config after editing the code a bit. Here's the JSON format:

Code:
{
    "scene1": {
        "inputs": {
            "0": {
                "gain": 1,
                "mute": true
            }
        },
        "outputs": {}
    },
    "scene2": {
        "inputs": {
            "0": {
                "gain": 10,
                "mute": false
            }
        }
    },
    "config": {
        muteWhenSpeaking: [1]
    }
}
Note: All scene names (along with config) and the Outputs and Inputs part are mandatory, but the strip numbers and effect (gain/mute) are optional (along with the muteWhenSpeaking part). Any strip numbers provided inside the muteWhenSpeaking array will be muted when the application is listening for the user's voice.

Press Ctrl + Alt + W. Make sure that this combination isn't used for any other application. There's no way to change it if you're using the EXE. If you're building the app yourself (see build instructions below), however, just edit the one-time-config.js by replacing Key parameter in the /keypress/addWebhook line with the key you want to assign. Then run node one-time-config.js.

Wait for a few seconds. A browser tab should open. Press Start Server. Say something like "Switch to [scene name]". It should switch scenes in OBS. If it says the scene doesn't exist, press F12. Go to the console section and press Ctrl + Alt + W again. Say the scene name again and see what it prints out. Sometimes you need to change the scene name in OBS. For example: "webcam" should be changed to "web cam" for it to work correctly. Please note: If you change a scene name or add a new scene in OBS, changes may take 5 seconds to reflect in the application. After switching scenes in OBS (using your voice), it should also change your Voicemeeter config a bit (according to your JSON).

Now change the scene in OBS (manually or through keyboard shortcut). Voicemeeter should change automatically too. And that's the magic of my application!

Using the in-built APIs

This application has a LOT of APIs. And all of them are exposed! Some of you will be muttering about security, but only the ports on your local PC is exposed. Here is a list of all the APIs that my application brings with it. Feel free to use any of them, but some of them (especially the ones on port 37492) may interfere with the application's internal functions. If something goes wrong, just re-install it and you should be fine!

Note: All endpoints are http GET unless specified explicitly

On port 23708

/ - Trump photo

/close - Quit application

/updateJSON (POST) - Update OBS/Voicemeeter scene link

/changeScene (POST) - Change scene through REST (both OBS and Voicemeeter are affected). Name in format: { "sceneName": "*name*"}

/keypress/addWebhook (POST) - Add webhook for any shortcut (Windows Key doesn't usually work). Send url and key in request body. Key in format Ctrl+Alt+W, etc.

/keypress/deleteWebhook (POST) - Delete an existing webhook. Send url and key in request body.

/obs/addWebhook (POST) - Add a webhook for an OBS event. Send url and event in request body. See here for a full list of possible events.

/shouldClose - Endpoint used internally by the application to determine if any open /voiceControl browser tabs should close (see /voiceControl). Gets either 'Yes!' or 'No!' as an answer.

/keypress - Used internally by the application to trigger the voice action. Request body should be in the following format:
{"key": 'Ctrl+Alt+W'}

/obs - Used internally by the application to trigger a change of scene. Request body should be in the following format:
{"updateType": "SwitchScenes", "scene-name": "scene1"}

/close - Used by /voiceControl browser application when it closes.

Build instructions

Download the ZIP file. Extract it. Open a new Command Prompt in the root location of the folder. Install packages with the command npm i. Change whatever you need to, and run the command npm run build. The EXE file should be generated at "./dist/OBS Voicemeeter Integration Server Setup x.x.x.exe".

Further resources

You can find the files for this application here. If you want to run only one of the four bits of this application (Voicemeeter, OBS, Voice recognition, Keyboard shortcut), you can find the APIs separately here.
