Which neural network is best for audio classification?

In the past decade, convolutional neural networks (CNNs) have been widely adopted as the main building block for end-to-end audio classification models, which aim to learn a direct mapping from audio spectrograms to corresponding labels.

How do you classify an audio signal?

There are two different types of audio signals: Analog and Digital signals.

Is CNN good for audio classification?

Convolutional Neural Networks (CNNs) have proven very effective in image classification and have shown promise for audio classification.

What is audio preprocessing?
