Audio Patches Overview

Spark AR Studio includes a wide range of audio patches. Use them to add effects like distortion and pitch changing to audio sources and to control how audio plays in your effects.

You can connect the output of the audio source, for example, the microphone or audio player, to multiple audio patches at once. This lets you process multiple audio signals running in parallel.

You'll need to render sound in your scene using a speaker, first. Audio patches should be connected to a patch representing the Audio property of the speaker.

Available Audio Patches

PatchDescription
Audio Analyzer

Estimate the bandwidth and full-band signal power (loudness) in a range between 0 (silence) and 1 (max). Stereo signals will be mixed together and treated as mono.

Audio Delay

Add a decaying echo effect to an audio source.

Audio Mixer

Use the Audio Mixer patch to combine the output from multiple audio sources, or audio streams.

Audio Player

Use the Audio Player patch to combine the audio clip in your project with either the Single or Multi-Clip Controller patch to play audio in your scene.

Bit Crusher

Connect the audio source you want to alter. For example, an audio clip, microphone or other audio source.

Compressor

Even out the loud and quiet parts of an audio clip or other audio source, so that both can be heard more clearly.

Denoiser

Remove background noise from an audio source.

Distortion

Distort the sound of an audio source. For example, to create a gritty or fuzzy sound effect.

Energy Meter

Estimate the signal power (loudness) of an audio input in a range between 0 (silence) and 1 (max).

Filter

Attenuate a range of frequencies.

Gain

Adjust the volume of an audio signal.

Instagram Music

Let people play tracks from the Instagram Music Library in an AR effect.

Multi-Clip Controller

Plays an audio clip multiple times in response to triggers, without stopping the clip when a new clip plays.

Oscillator

The Oscillator patch generates sound signals in specific waveforms or tones. Learn how to use an Oscillator to make your own synthesizer.

Parametric Equalizer

A three-band parametric equalizer and filter. Use this patch to shape audio by boosting or cutting areas of frequency.

Pitch Shifter

Change the pitch of an audio source.

Reverb

Add a sense of space or depth to an audio source.

Ring Modulator

Create an oscillating sound effect with varying pitches.

Single-Clip Controller

Play, stop or loop a single audio clip based on a specific trigger.

Vocoder

Use the Vocoder patch to create robotic, synthesized-style sound effects.
