🎵 Audio Visualizer

📌 Overview

The Audio Visualizer is a real-time audio visualization project built using Python. It captures live audio, processes it using Fast Fourier Transform (FFT), and displays a dynamic visual representation of the sound frequencies using Pygame.

✨ Features

• 🎙️ Real-time audio capture using sounddevice
• 📊 Fourier Transform (FFT) for frequency analysis
• 🎨 Dynamic bar visualization based on frequency magnitude
• 🎧 Microphone test utility to ensure audio input is working
• 📦 Minimal dependencies for easy setup

🛠️ Installation

1. Clone the repository:

   git clone https://github.com/isthatlak/Real-Time-Audio-Visualizer.git
   cd Real-Time-Audio-Visualizer

2. Create a virtual environment (recommended):

   python -m venv venv
   source venv/bin/activate  # macOS/Linux
   venv\Scripts\activate    # Windows

3. Install dependencies:

   pip install -r requirements.txt

🚀 Usage

1️⃣ Test Microphone

Check if your microphone is working properly:

python test_mic.py

2️⃣ Capture and Playback Audio

Record a short audio clip and play it back:

python audio_capture.py

3️⃣ Run the Visualizer

Launch the real-time audio visualizer:

python visualizer.py
