Screm Bot 3000

Overview

I like playing comedic sound effects while streaming videogames but couldn't find a sound board program that let me configure my sound effects and keyboard shortcuts with Git version control while also randomizing the sound effects that were played (it's more fun if I'm surprised by the sound effect as well as my viewers). I also wanted my Twitch chat to be able to trigger sound effects via a chat command (!sfx). Thus, Screm Bot 3000 was born!

Usage

1. Create a config.toml file as outlined in the "Config File" section below
2. Put any sound effects you want to use in ./sounds inside a directory with a name something like ./sounds/e-epic
   • The first letter of the directory name (e.g. e in the example above) is the keyboard button used to play a random sound file from that directory (Alt + e in this case)
3. Launch screm.exe by double clicking on it
4. Trigger a sound effect with your configured keyboard shortcuts!

Config File

config.toml should be in the same directory as the screm.exe binary. There are a few properties that can go in your config.toml file. Properties listed below are optional unless otherwise noted. See sample-config.toml for an example with fake configuration values.

• twitch_username (required): The username for your Twitch account/channel. Screm Bot 3000 can't read your channel's chat messages without this.
• twitch_bot_username (required): The username for the Screm chat bot. Can be the same as twitch_username.
• twitch_secret: The OAUTH token for the twitch_bot_username account. Needed to post messages to your Twitch chat.
• twitch_authorized_users: A list of Twitch usernames for users authorized to trigger sound effects on your stream from Twitch chat.
• welcome_message_enabled: Whether or not Screm Bot 3000 should automatically welcome non-bot viewers to your channel (defaulted to false).
• disable_keyboard_shortcuts: If you don't want to automatically configure keyboard shortcuts (because you use another soundboard program like an Elgato Stream Deck), you can set disable_keyboard_shortcuts to true (defaults to false) and Screm Bot 3000 will only listen for Twitch chat messages.

FAQ

Does this work on any operating systems besides Windows?

No. Not at the moment at least. The library I'm using for capturing global keyboard shortcuts is Windows-specific and my use case only involves Windows.

Why does the program instantly crash when I open screm.exe?

You likely don't have a valid config.toml created. Try running the program with go run main.go to get a more helpful error.

The Windows Sound Mixer can't change the output device of screm.exe.

I know. It's a bug somewhere in the audio library used by Screm Bot 3000. Follow the steps below to fix it every time you launch screm.exe. If it doesn't work the first time, try again. The workaround's fiddly.

1. Open "Sound Mixer"
2. Change your default sound output device (the dropdown near the top of the page) from its current device (e.g. "USB Sound Card") to whatever device you want Screm Bot 3000 to output to (e.g. "VoiceMeeter Input")
3. Start screm.exe
4. Play a sound effect with a keyboard shortcut
5. While the sound effect is playing:
   1. Switch screm.exe's output to your desired output (e.g. "VoiceMeeter Input")
   2. Change the default sound output to the previous value (e.g. "USB Sound Card")
6. Verify that sounds from various programs are going through your desired outputs
