NVDA Voicemeeter

A remote control app for Voicemeeter, designed to be used with the NVDA screen reader.

For an outline of this projects goals see the SPECIFICATION.

Requirements

• NVDA screen reader
• NVDA's Controller Client files
• Python 3.10 or greater

Installation

From Source

First clone the source files from this repository and install the dependencies.

git clone https://github.com/onyx-and-iris/nvda-voicemeeter.git
cd nvda-voicemeeter
pip install .

Then download the Controller Client and place the dll files into the directory controllerClient.

Your directory structure should look like this:

├── controllerClient/

        ├── x64/

                ├── nvdaControllerClient64.dll

        ├── x86/

                ├── nvdaControllerClient32.dll

From Releases

If you want to get started quickly and easily I have uploaded some compiled versions of the app in the Releases section.

Run

Once the repository is downloaded and the controller client files in place you can launch the GUI with the following __main__.py:

import voicemeeterlib

import nvda_voicemeeter

KIND_ID = "potato"

with voicemeeterlib.api(KIND_ID, sync=True) as vm:
    with nvda_voicemeeter.draw(KIND_ID, vm) as window:
        window.run()

KIND_ID

May be one of the following:

• basic
• banana
• potato

Use

Tabs

The app presents four tabs Settings, Physical Strip, Virtual Strip and Buses. Navigate between the tabs with Control + TAB and Control + SHIFT + TAB or once focused on any tab, Left and Right arrow keys.

All controls within the tabs may be navigated between using TAB.

Settings

The following controls offer context menus accessed by pressing SPACE or ENTER:

• Hardware In
• Hardware Out
• Patch Composite

Press ESCAPE to exit any context menu.

All other buttons can be triggered by pressing SPACE or ENTER.

To adjust Patch Asio Inputs to Strips and Patch Insert values use UP and DOWN arrows when in focus.

To access Advanced Settings you may press the Advanced Settings button or use Control + A when in the Settings tab.

Strip/Bus

To rename a strip/bus channel navigate to the relevant tab, then press F2. This will open a popup window where you can set the channel index (with a spinbox) and set the new label using a text input box.

Pressing the OK button with an empty text input will clear the label. In this case the label will be read as a default value for that channel. For example, if the leftmost Strip label were cleared, the screen reader will now read Hardware Input 1.

Pressing Cancel will close the popup window with no affect on the label.

Menu

A single menu item Voicemeeter can be opened using Alt and then v. The menu allows you to:

• Restart Voicemeeter audio engine
• Save/Load current settings (as an xml file)
• Set a config to load automatically on app startup.

The Save Settings option opens a popup window with two buttons, Browse and Cancel. Browse opens a Save As dialog, Cancel returns to the main app window.

Load Settings and Load on Startup both open an Open dialog box immediately.

If you have any questions/suggestions feel free to raise an issue or open a new discussion.
