While we are on the subject of Chordata, it was created with another very interesting piece of software called CLAM. CLAM is a software framework for research and application development on the audio and music domain. It provides means to perform complex audio signal analysis, transformations and synthesis. It also provides a uniform interface to common tasks on audio applications such as accessing audio devices and audio files, thread safe communication with the user interface and DSP algorithms recombination and scaling.
You can use CLAM as a library to program your applications in C++ but you can also use graphical tools to build full applications without coding. For those of you looking to try your hand at programing this allows for you to get your feet wet without having to full on learn C++. While this program will take some time to learn, it bears much promise and is capable of building software such as Chordata. CLAM can be found here.
