Creating audio effects

This article continues from the previous article, and assumes you have an Oscillator Node, a Gain Node, and an Audio Destination Node already placed and you can hear the sound you made. It is also assumed you have basic understanding on how to use the Patcher, as described in the previous articles.

Once you have a basic sound coming from an Oscillator Node, it is time to add some spice to it.

Pre-built Effects

AudioNodes has a lot of ready-to-use audio effects that you can just drop in, wire up, and tweak to your liking. One commonly used effect is the convolver/reverb effect, which adds immense depth to your sound. In AudioNodes, this is done by the Convolver Node, which can either generate the effect, or use an impulse response file.

You already know how to insert new Nodes between existing ones, so feel free to go ahead and drop in a Convolver Node between the Oscillator Node and the Gain Node (or between the Gain Node and the Audio Destination Node, the result will be very similar).

Feel free to tweak it to your liking.

Combining Multiple Sounds

The Add (Audio/Control) Node can be used to combine multiple audio sources. It has multiple inputs and a single output. Let’s go ahead and make another Oscillator Node by cloning our current one: right click on it (or touch and hold), then use the Clone option. Now add an Add (Audio/Control) Node, and wire up our Oscillators into it:

More inputs can be activated on the Add (Audio/Control) Node from its properties panel, allowing you to combine even more audio sources.
