Audio Classification Project with Convolutional Neural Networks (CNNs)

## 📌 Project Overview
8+
9+
This project demonstrates how to classify audio files using Convolutional Neural Networks (CNNs). Since raw audio signals are one-dimensional and CNNs are highly effective with image data, we first convert audio files into spectrogram images. These images visualize the frequency spectrum over time and serve as the input for our deep learning model.
10+
11+
The trained model can distinguish different audio classes based on learned patterns from spectrograms, providing an efficient and accurate approach to sound recognition.
