Sigourney is a modular audio synthesizer.

It is mostly written in Go, with a thin layer of JavaScript to provide the UI.

Sigourney has been developed under Mac OS X 10.9. It may run on other platforms, but I can only vouch for this one. In the future Sigourney should run on OS X, Linux, and Windows.

First, install Go. (Make sure you set GOPATH.)

Second, install portaudio. I used Homebrew to do this under OS X.

$ brew install portaudio

Third, download (or update) and build Sigourney and its dependencies:

$ go get -u github.com/nf/sigourney

Run the sigourney binary (which should be in $GOPATH/bin) from the repository root directory:

$ cd $GOPATH/src/github.com/nf/sigourney
$ $GOPATH/bin/sigourney

Then open http://localhost:8080/ in your web browser. (I have only tested with Google Chrome.)

At this point you should see a page with an "engine" module in the middle and a list of modules in the top right. Drag the "sin" module somewhere onto the canvas. Then you can click to draw a connection from the "sin" module's output to the "engine" module's input. At this point you should hear a 440hz sine wave. If not, something is wrong.

The project was originally named "gosynth" but a friend told me in no uncertain terms that I needed a better name. Around that time, my pet rabbit Sigourney died, and so I decided to honor her memory with this project.

I like the name because Sigourney liked to hang out in my studio and listen to the music. (It's also convenient that it has "go" in it.)
