MixIT Conference: »Jay-Z, Maths and Signals! How to clone Shazam »
Presented by Moustapha Agack, Friday April 14, 2023 was for me one of the highlights of MixIT, a Lyon event of discovery and friendly meetings, dedicated to IT. The title of the conference caught my attention and I was eager to learn more about how to recreate Shazam or similar app.
Moustapha's presentation was incredibly dynamic, he managed to popularize the most complex concepts, while playing music in the background. To begin with, he explained the composition of sound, characterized by frequency and amplitude. Then he introduced Fourie's transformationr which allows to recover the fundamental of sound.
Moustapha compared the fundamentals of each music by comparing them to those of his database stored in JSON. For this, he used the Fast Fourier Transform in Javascript, based on the Colley-Tuket algorithm.
After some mathematical considerations and a really nice demo, we could see that his application worked very well with a reliability of 90%.
Of course, we're still a long way from the deep analysis (and its dollars) of Shazam, but the result is there.
In short, the presentation was a demo of a fellow developer's project, with an introduction to the different concepts needed to get started developing an application of this type.
I loved the subject and the presentation, it also refreshed my memory of Fourier transformations and I already have new ideas on my list of projects related to the work of Joseph Fourier. In short, this conference gave me new ideas for dev, always for the moment when this one will be online!
