Output data format (to be predicted by the network) Note the kick drum on each beat in the lowest frequency bin. The values (pixel colour) then indicate the intensity of the audio signal at each frequency and time step.Īn example frequency spectogram from a few seconds of electronic music. These basically contain time on the x-axis, and frequency bins on the y-axis. I figured a frequency spectogram would serve as an appropriate input to whatever network I was planning on training. I don’t know a whole lot about the physics side of audio, or frequency data more generally, but I am familiar with Fourier analysis, and spectograms. One of the first decisions to make here is what general form the network’s input should take. Initially I had to throw around a few ideas regarding the best way to represent the input audio, the BPM, and what would be an ideal neural network architecture. After a small experiment a while back, I decided to make a more serious second attempt. I have always wondered whether it would be possible to detect the tempo (or beats per minute, or BPM) of a piece of music using a neural network-based approach. ![]() ![]() ![]() Detecting Music BPM using Neural Networks
