Cybr Audio Server

The cybr server is a companion to the fluid-music JavaScript library. When using cybr with fluid-music, you can:

• Play and render audio from JavaScript
• Use and configure VST plugins from JavaScript

To get the most out of the the Fluid Music system, you will want to run an instance of cybr alongside your JavaScript code.

Development

cybr uses git submodules for managing dependencies. You can checkout all the dependencies with the following command:

git clone https://github.com/fluid-music/cybr.git
cd cybr
git submodule update --init --recursive

To build cybr, open cybr.jucer using the Projucer and create an IDE project for your platform. cybr.jucer supports the following development environments:

• Windows: Visual Studio
• MacOS: XCode
• Linux: Makefile

Note that by default, cybr.jucer expects you to have a version of the Projucer compiled in GPL mode. If you downloaded the Projucer from the JUCE website, it will not be in GPL mode and you may need to update cybr.jucer by removing JUCER_ENABLE_GPL_MODE=1 from the "Preprocessor Definitions" textbox.

Building for Linux

You have two options when compiling for linux:

1. Use the default Makefile - Do this if you want to avoid the Projucer, and you want to accept all the default build options.
2. Use the Projucer to generate a customized Makefile - Do this if (for example) you want to compile without Jack support or without VST support.

1. Building for Linux - Default Makefile

Make sure that you have the Jack development files installed. Then run make.

sudo apt install libjack-jackd2-dev # Ubuntu/Debian
cd Builds/LinuxMakefile/
make                     # build debug binary
env CONFIG=Release make  # build release binary

2. Building for Linux - Custom Builds

First open cybr.jucer in Projucer.

If you do not need JACK support, disable it in the projucer project via modules -> juce_audio_devices -> JUCE_JACK. If you leave JACK enabled, make sure that you have the JACK development files installed:

sudo apt install libjack-jackd2-dev # Ubuntu/Debian

Save the cybr.jucer project with ^+p. This will generate a makefile in Builds/LinuxMakefile/Makefile.

cd Builds/LinuxMakefile/
make                     # build debug binary
env CONFIG=Release make  # build release binary

CLI

The most common invocation is cybr -e -f, which opens an empty document (-e) and starts a server listening for fluid-music recipes (-f). Recipes can then be sent from fluid-music client code.

For up-to-date info on all the possible commands, run cybr -h.

For detailed information about an option, (ex -f) run cybr -h -f
