![]() The adc node is often used as an audio input, but it can also be used to pass a gate signal from a modular synth. The adc node outputs an audio signal, but in this case, all that means is that incoming signals are clamped between -1 and 1. An external source could be a microphone, a DAW, or a CV input from a hardware modular synth. The adc node is how you get audio and CV into Audulus from an external source. The zero cross node analyzes incoming audio and outputs its frequency in hz.Īccess to 1 of 16 channels indexed from 0.The timer node has a variety of uses including creating envelopes and driving automation.The text node is used for labeling and commenting inside of patches.The adc and dac nodes are used to get audio and CV in and out of Audulus.Util nodes are various utilities that do some very essential things. If a node is not connected to an output, it will not be evaluated. Examples of outputs are value, light, and dac nodes. Utilities for creating and managing polyphonic signals Tools for adjusting and analyzing signal levelsĮssential primitive-level synthesis tools Use math and logic to manipulate and create signals The table below lists each category and provides a short description. There are 10 different categories of nodes. ![]() Other nodes have attributes you can change directly on the node. If a node is exposable, a node will have an (x, y) coordinate for where it is inside the module and another (x, y) coordinate for where it is on the UI of the module. Some, like the knob node, are automatically exposed while others, like the text node, have an option to expose. Some nodes are exposable, meaning they have some element that can appear on UI of a module. Modules are containers for nodes that allow you to create a user interface for you to interact with. Nodes can be packaged into modules and submodules. Every node has an (x, y) position attribute in this panel. Some nodes have attributes that are accessible in the inspector panel. Negative hz signals can be used to flip the phase of the phasor node, useful for through-zero FM. : Hz values above sampleRate/2 can be generated but are limited in use. : Audio signals can exceed the -1 to 1 range, but they will be clipped to that range upon output. signalĪny signals can be any number and type of signalĠ or high where high is any non-zero positive 32-bit number. The table below describes every type of signal that nodes use. : Audulus signals are signed 32-bit floats. These categories are defined by their range, unit, and how they are used. Although all signals are numbers, there are several categories of signals. Nodes send and receive signals through wires. However, overall signal flow in Audulus is from left to right. Wires can go from any output anywhere to any input anywhere: up, down, left, or right. To connect multiple wires to one input, you must use an add node to first add the signals together. Wires cannot be disconnected from an output. You disconnect nodes by unhooking a wire from an input. You can connect one output to as many inputs as you want. You cannot drag a wire from an input to an output. You connect nodes together by dragging a wire from an output to an input. Nodes can be moved around the canvas, but they cannot be rotated. Outputs are on the right side of nodes and are red. Inputs are on the left side of nodes and are blue. A node may have inputs, outputs, both, or none. Nodes are packets of code that do things. Everything in Audulus is built with nodes.
