AudioIO

Notes:

• This library is a work-in-progress. Some graphs are incomplete or broken!
• Test coverage isn't 100%, nor will it ever be. Some Nodes can only really be tested by ear.
• Documentation is inbound in the near future.
• Since this is still pre-alpha, the spec/API might change. There are also a few inconsistences here and there that are known about and will be fixed up!

About

AudioIO is a modular component system for building complex instruments, effects, and audio signal graphs using the WebAudio API, similar to NI's Reaktor, PureData, or Max/MSP.

The goal behind this library is to elimate the need to use expensive ScriptProcessorNodes and instead pass these calculations through "native" WebAudio components. This allows for a much more efficient way of building audio effects and instruments.

Features

• Perform both basic (add, subtract, multiply, divide), complex (abs, sin, cos, tan, max, min, sqrt, reciprocal, pow, etc.), and binary (AND, OR, NOT) maths on audio signals.

• Perform comparisons between audio signals (>, <, ===).

• Emulate JS logic features such as switch and if/else

• Calculate phase offsets for oscillators using only WebAudio components.

• Allow for easy creation of envelopes, and oscillators with unison, glide, and polyphony properties.
