CorsairKeyboardSpectrograph | Spectrograph audio visualizer for Corsair K70 RGB keyboard

CorsairKeyboardSpectrograph is a C++ library. CorsairKeyboardSpectrograph has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This is a simple audio input visualization that uses the K70 LEDs as a "bar graph" of sorts for the audio spectrum. It also continuously cycles through a dim rainbow pattern as the background for this visualization. Audio comes from the default input device, so if you want to use it to visualize the output audio you must use some form of a loopback device. In Linux you can use PulseAudio’s monitor inputs to get a digital loopback while in Windows many audio chipsets have an internal "Stereo Mix" or similar loopback. Failing that, there are programs like Virtual Audio Cable that can do a softare loopback in Windows.
