During first lesson of Practical Deep Learning for Coders course, Jeremy had mentioned how using simple computer vision model by being a bit creative we can build a state of the art model to classify audio with same image classification model. I was curious on how I can train an music classifier, as I have never worked on audio data problems before.

You can find how I trained this music genre classification using fast.ai in this blogpost..

Dataset

1. The competition data
2. Image data generated from converting audio to melspectograms in form of images

Training

Fast.ai was used to train this classifier with a ResNet50 vision learner for 10 epochs.

Examples

The example images provided in the demo are from the validation data from Kaggle competition data, which was not used during training.
