In deep learning, a convolutional neural network (CNN, or ConvNet) is a class of artificial neural network (ANN), most commonly applied to analyze visual imagery. CNNs are also known as Shift Invariant or Space Invariant Artificial Neural Networks (SIANN), based on the shared-weight architecture of the convolution kernels or filters that slide along input features and provide.

We will start with sound files, convert them into spectrograms, input them into a CNN plus Linear Classifier model, and produce predictions about the class to which the sound belongs. Audio Classification application (Image by Author) There are many suitable datasets available for sounds of different types.
Audio Handling Basics: Process Audio Files In Command-Line or Python. This article shows the basics of handling audio data using command-line tools. It also provides a not-so-deep dive into handling sounds in Python. The two basic attributes of sound are amplitude (what we also call loudness) and frequency (a measure of the wave’s vibrations.
Let X be the matrix containing your features which you have extracted using fft. T is your target vector where T (i) = 0, if your i-th sound file contains normal sound, and T (i) = 1, if your i-th sound file contains the sound of breaking glass. You set the layer size of your neural network: layerSize = 10; and initialize your network.
It may seem not intuitive to utilize convolutional neural networks to perform sound classification, but the theory is actually quite simple — all audio can be represented with a spectrogram image,.
