Spectrogram of swelling trumpet sound
Art+Logic’s Incubator project has made a lot of progress. In a previous post I mentioned that Dr. Scott Hawley’s technique to classify audio involved converting audio to an image and using a Convolutional Neural Network (CNN) to classify the audio based on this image. That image is a spectrogram. I’m going to go into some detail about what we do to create one, and why to the best of my ability.
Computers have been around for less than 100 years. In that short period of time, some incredible things have happened: they’ve been universally adopted so quickly that we have them in our houses. In our cars. Even in our pockets. In the last 40 years, there have been many significant events when it comes to computers:
Similarly to those past events, an important development in computer science which has the potential to significantly impact the way we develop applications is machine learning and artificial neural networks.

friz—a Flexible Animation Controller for JUCEAs is often the case, I found myself working on a personal project and had some UI elements that really wanted to have some life to them on the screen.
I tucked into the JUCE documentation expecting to see something that I could use to easily add some personality to the interface, and…didn’t find what I was looking for. There’s a ComponentAnimator class that supports moving a single component from one set of coordinates/bounds to another linearly, and also modify the component’s alpha value to have it fade in or out.
I was looking for something…more expressive.
Art+Logic has kicked-off its first software Incubator project, and I was selected to handle the development effort. After meeting Dr. Scott Hawley and being briefed on the technique he uses for classification of audio files using neural networks (NN), and determining current and future features, we were ready to begin the project. While we go through this process, I’ll be documenting it on this blog. (more…)
Python is a powerful programming language with extensive library support. But what does one do when needing to integrate with a platform specific C or C++ component that has no native python support? There are two options. Completely rewrite the functionality in python or create a python extension. Either option can be painful and prone to errors. Enter Cython. It’s like the peanut butter and the jelly to the extension sandwich. (more…)
