The time period of the stripes movement is set to the BPM of the song.В Beat detection is used to transition the camera angle. The smoothed volume is used to determine the size of the central white shape. In the ГњberVizВ demo the levels data sets the thickness of the colored strips. analyser.getByteFrequencyData(freqByteData) Using the WebAudio API this call will get the levels as an array of numbers between 0 to 256, where 0 indicates silence. They can be visualized as a bar chart or a 1980вЂ™s graphic equalizer. The levels are an array of amplitudes for each frequency range. The volume is also used to give a little bounce on the height of the waveform. The Loop Waveform VisualizerВ draws the waveform data into circles that expand from the middle of the screen. The waveform is the shape of the sound wave as it flies through the air and hits your ear.В With the Web Audio API, use this call to get the waveform as an array of numbers between 0 and 256, where 128 indicates silence: analyser.getByteTimeDomainData(timeByteData) Beat detection is also used to trigger the material textures switching out. In the ParadoliaВ demo, the volume is used to determine the brightness of the lights in the scene.

Simple volume tracking can be enough to give a nice synced feel. Volume data can be used raw or eased over time to give a smoother value: smoothedVolume += (volume - smoothedVolume) * 0.1 The volume is the current global amplitude or loudness of the track. Drag and drop an MP3 file to play it, or switch to the mic input with the control panel at right. To see what these look like, view the Audio Analysis Demo. The white line above the volume bar indicates the beat threshold.

Beat DetectionВ вЂ“ the volume bar flashes white when a beat is detected.

LevelsВ вЂ“ the bar chart of frequency amplitudes, from bass on the left to treble on the right.

VolumeВ вЂ“ the thicker bar on the right hand side.

There are 4 main pieces of data we can extract: To sync to an audio input, we need to analyseВ the audio stream in realtime. The demos below work in Chrome using Three.js and the Web Audio API, but the same principals apply if you are using Processing, OpenFrameworks or some other framework.

This can be useful for вЂњHands Free VJingвЂќ, allowing you to sit back and have the visuals automatically sync, or inВ a video game where you want some part of the visuals to react to the soundtrack. Here I want to talk about the last method. Audio Reactive вЂ“В code driven visuals that automatically adapt to a live audio input.Midi Input вЂ“ if you have access to the musicвЂ™s midi data, this can be a great way to drive visuals.Sequencing вЂ“ pre-analyzing the music and scripting an animation as a list of timecoded events.
