luxaudio

❤️💚💙

luxaudio is a Go application that captures audio, does spectral analysis on it, and sends a spectrum visualization to a luxsrv-enabled RGB LED strip over the network.

luxaudio is part of Lux.

Requirements

  • Go

Quick Start

Build

go build ./cmd/luxaudio

Start

./luxaudio \ --channels 1 \ --device capture \ --host 10.10.10.108 \ --leds 120 \ --sampleRate 44100 \ --fft 1024 \ --decay 0.5 \ --dbfsThreshold -64 \ --audibleLow 30 \ --audibleHigh 17000 \ --color 9dfc03 \ --mirror true 

Usage

Usage of ./luxaudio: -audibleHigh float upper audible frequency (default 20000) -audibleLow float lower audible frequency (default 20) -backend string audio backend (auto, wasapi, alsa, pulse, jack) (default "auto") -channels int number of channels (default 2) -color string hex color (default "ff00ff") -dbfsThreshold float dBFS threshold (default -96.32959861247399) -decay float decay factor [0,1] controls the smoothness of the visualization (default 0.5) -device string device to use (loopback, capture) (default "loopback") -effect string color effect (solid, rainbow, luxception) (default "solid") -fft int FFT size (default 1024) -host string host of the luxsrv -leds int number of LEDs to be driven (max 255) -mirror mirror mode with lower frequencies at the middle -port uint port of the luxsrv (default 42170) -sampleRate int sample rate -verbose print verbose messages
