Although deep learning eliminates the need for hand-engineered features, we have to choose a representation model for our data. Instead of directly using the sound file as an amplitude vs time signal we use a log-scaled mel-spectrogram with 128 components (bands) covering the audible frequency range (0-22050 Hz), using a window size of 23 ms (1024 samples at 44.1 kHz) and a hop size of the same duration.
The deep learning stage takes place offline using a large database of human speech. The goal of the learning is to identify and separate human speech from any environmental noise. The result is a deep neural network that can identify in real-time precisely when and where in an audio signal the human voice is present.

It demonstrated that the technique of classification, a form of supervised learning, could be employed to approximate the ideal binary mask as a way of separating speech from noise. With classification, a machine mimics human learning, in effect, by completing exercises, receiving feedback, and drawing and remembering lessons from its experiences. The process of learning is called training a Deep Learning or AI model. Let's say the deep learning model is a black box with millions of filters. At the very beginning, we teach the model to learn a specific task based on examples. In the case of developing DeNoise AI, our image noise reduction software, we give the black box a noisy picture ...

3.1 Noise reduction: The Noise Reduction algorithm uses Fourier analysis. It finds the spectrum of pristine tones that make up the background noise in the susurration segment that you culled - that's called the "frequency spectrum" of the sound. That forms a dactylogram of the static background noise in your sound file.
