"Wouldn’t it be cool if…"

We’ve all had that thought about something. How do you get from there to a product you can use and share with others? When I found myself playing with an idea that seemed exciting and new, I decided to capture some notes on the process, from the perspective of an Engineering Manager at a company that’s all about implementing people’s creative visions.

Making Spectrograms in JUCE

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.

Discover Machine Learning

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:

  • Continuous decrease in size and increase in power.
  • Access to computing at home and at work.
  • Networking, the spread of the internet, and acceptance of the web.
  • Computers in our hands (cell phones).

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.
