Mx. Voice is free, open-source software available for macOS, Windows, and Linux.
Download the latest version:
- macOS (DMG) — Universal binary for Intel and Apple Silicon
- Windows (EXE) — 64-bit installer
- Linux — AppImage and .deb packages available on GitHub
Once downloaded, install the app the same way you would any other application on your platform. On macOS, open the DMG and drag Mx. Voice to your Applications folder. On Windows, run the installer and follow the prompts.
When you first launch Mx. Voice, you’ll see the Profile Launcher. Profiles let you maintain completely separate configurations — different hotkey setups, holding tank lists, and preferences for different shows, venues, or performers.

On your very first launch, a Default User profile is created automatically. You can use it right away, or create a new one:
Select your profile and click Choose Profile to launch the main application. You can switch profiles later from the View menu.
Before importing songs, you’ll want to set up a few directories. Open preferences from View → Preferences in the menu bar.

| Setting | What It Does |
|---|---|
| Audio Files Directory | Where your audio files are stored. When you import songs, files are copied here. Set this before adding any songs. |
| Database File Location | Where the song database lives. The default location works well for most users. |
| Hotkeys / Holding Tank Directory | Where saved hotkey and holding tank configuration files are kept. |
Categories help you organize your audio library. Each category has a short code (up to 4 letters) and a description. For example:
| Code | Description |
|---|---|
| COMM | Comedy |
| MUSC | Music |
| SFX | Sound Effects |
| MONS | Monologues |
You can create categories from the main application interface before or during song import. The category code is auto-generated from the description if you don’t specify one.
There are two ways to add songs to Mx. Voice:
The fastest way to populate your library is to import an entire folder of audio files at once.
Mx. Voice will scan the directory (including subfolders), extract metadata like title, artist, and duration from each file, and copy them into your configured audio directory.
Supported audio formats: MP3, WAV, OGG, FLAC, M4A, MP4, AAC
You can also add songs one at a time, which gives you more control over the title, artist, and category for each file.
The main Mx. Voice window is divided into three columns:
| Column | Purpose |
|---|---|
| Left — Holding Tank | A staging area for songs you want quick access to, with storage and playlist modes. |
| Center — Search | Search and browse your entire song library by category, title, artist, or tags. |
| Right — Hotkeys | Assign songs to F1–F12 keys for instant playback during a show. |
To play a song:
You’ll see a waveform visualization and playback progress. Use the controls to pause, stop, adjust volume, or fade out.
