hxaudio

hxaudio is a wrapper for grig.audio that makes it easier to use with less boilerplate.

Supports WAV, OGG, and MIDI playback, plus FFT-based frequency analysis.

Installation

Examples

Playing a sound

var engine = new hxaudio.AudioEngine(null, new hxaudio.AudioOutput());
engine.start();

Sound.load("music.ogg").play();

Microphone input

var input = new hxaudio.AudioInput();
input.onProcess = (sample:Float) -> trace(sample);

var engine = new hxaudio.AudioEngine(input, new hxaudio.AudioOutput());
engine.start();

FFT analysis

var analyzer = new hxaudio.Analyzer();
engine.onPostProcess = (l, r) -> analyzer.feed(l, r);

var bands = analyzer.getBands(32); // 32 bands, normalized 0..1

Raw output

var output = new hxaudio.AudioOutput();
output.onProcess = () -> output.write(Math.random(), Math.random());

var engine = new hxaudio.AudioEngine(null, output);
engine.start();

Dependencies

• grig.audio - Literally what makes hxaudio exists
• format - WAV parsing
• stb_ogg_sound - OGG decoding
