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

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
