radiant-voices 0.1.0

Create, read, modify, and write SunVox files.

Overview of Radiant Voices

Part of the Metrasynth project.

Radiant Voices provides tools to create, read, modify, and write SunVox files. This includes project files ending in .sunvox, and module/synth files ending in .sunsynth.

SunVox data structures and APIs

Radiant Voices has nearly 100% coverage of all data structures used by SunVox files, exposing a “Pythonic” API for creating and manipulating those structures.

Using the API, you can do things not possible with the standard SunVox interface or the SunVox DLL, such as:

• algorithmic composition

• parametric synth/module design

• structure and complexity analysis

• automatic graph layout of modules

• and more…

Our collective imagination is the limit!

Interaction with the SunVox DLL

By combining Radiant Voices with sunvox-dll-python, one can also create alternative editing and performance tools to use alongside, or instead of, the official SunVox app.

The two packages work together to provide convenient high-level APIs for loading project and module objects directly into playback slots managed by the SunVox DLL.

Some possibilities might include:

• alternative project editors

• generative sound design using genetic algorithms

• network-enabled performance tools

What can you come up with?

SunVox file format documentation

Radiant Voices intends to serve as a de facto source of documentation about the format, as there is currently no official documentation for the SunVox file format.

The interpretation of SunVox file formats is based on a mix of “clean room” style inspection of what SunVox writes to disk when a file is edited a specific way, as well as the most recent BSD-licensed source code for the SunVox audio engine.

Requirements

• Python 3.5

• OS supported by sunvox-dll-python, if working with SunVox DLL.

• GraphViz, if you want to make use of module auto-layout features.

Quick start

The “hello world” example will construct a SunVox project in memory containing a FM module connected to the Output module. It will then load it into the SunVox DLL and send a single note-on command to the FM module:

$ pip install radiant-voices
$ git clone https://github.com/metrasynth/radiant-voices
$ cd radiant-voices/examples
$ python helloworld.py
