Udemy Audio Classification using Convolutional Neural Net [TUTORiAL]

This course is designed to provide a real understanding of handling audio files in machine learning. This course will give you a complete track record of processing audio files from A to Z using Python. This course will explain how to use Convolutional Neural Networks to generate an H5 AI model for audio classification purposes.

This course gives you a complete understanding of Raspberry Pi 5 assembly, programming, AI Model deployment, and prediction of audio files. We will learn how to identify audio environments for machine-learning purposes. We will learn how to record audio files and slice them into clips of positive and negative types. How to process the raw audio clips and inject the “keyword” to be detected by the neural network.

Apply clip labeling, clip slicing, and clip batching for the preparation of feeding audio clips to the Neural Net. Apply the required stages (load, time domain, frequency domain, spectrogram, and resize) to process raw audio clips for prediction use. Use Python programming to generate an H5 AI model for audio prediction purposes. Deploy and run the H5 AI model inside the Raspberry Pi 5 to control the movement of the servo motor with audio order. Testing the model with a real-time audio prediction process.

What you'll learn:

• Define the real Audio Environments to record clips for Machine Learning Model Prediction.
• Compose Negative and Positive Audio Clips for Machine Learning use.
• Inject “Audio Keyword” to trigger RASPI 5 processor action in Positive Audio Clips.
• Slice an Audio file into several Audio Clips for Neural Net feeding.
