Open Blaster is an open source crossplatform CLI utility for controlling Sound Blaster sound cards from command line

Currently supported devices

• Sound Blasterx G6

Getting started

clone this repository

install dependencies

openblaster requires hidapi for communicating with the hardware and json-c for parsing EQ presets

both can be installed with Homebrew on macOS and should be available on your distro's package manager of choice.

brew install json-c hidapi

generate build files

cmake -S . -B build

build the executable

cd build && make

run

./openblaster

Usage

When you run openblaster without any arguments, help is automatically output

Usage: openblaster [-r,g,b int value] [-e /path/to/json]

-r -g -b are color values [0-255] for the LED if available on your soundcard

-e is the path to your EQ preset. Right now compatible with the exported presets from the Sound Blaster Command software
