xmm-lfo

waves-lfo wrappers of xmm-client classes

See waves-lfo from the wavesjs library and xmm-client.

installation :

npm install [--save] wavesjs/waves-lfo

The application consuming the xmm-lfo module (aka plugin) must also import the waves-lfo library

npm install [--save] wavesjs/waves-lfo

es6 example :

import * as lfo from 'waves-lfo/client';
import { PhraseRecorderLfo, HhmmRecorderLfo } from 'xmm-lfo';

const eventIn = new lfo.source.EventIn({
  frameSize: 6,
  frameType: 'vector',
  frameRate: 0,
});

const xmmRecorder = new PhraseRecorderLfo({
  columnNames: [
    'accelX', 'accelY', 'accelZ',
    'rotAlpha', 'rotBeta', 'rotGamma'
  ],
});

const hhmmDecoder = new HhmmDecoderLfo({
  likelihoodWindow: 3
});

eventIn.connect(xmmRecorder);
eventIn.connect(hhmmDecoder);

if (window.DeviceMotionEvent) {
  window.addEventListener('devicemotion', function(e) {
    eventIn.process(Date.now(), [
      e.acceleration.x, e.acceleration.y, e.acceleration.z,
      e.rotationRate.alpha, e.rotationRate.beta, e.rotationRate.gamma
    ]);
  });
}

eventIn.start();

// to start / stop recording :
xmmRecorder.start();
xmmRecorder.stop();

// when stop() is called, a promise updates the internal phrase that can
// be obtained by calling getRecordedPhrase() :
let phrase = xmmRecorder.getRecordedPhrase();

// once a model has been trained by xmm-node from the recorded phrases, it can
// be passed to the decoder like this :
hhmmDecoder.params.set('model', someModelFromXmmLibrary);
