Yaman Music Classification

Traditional music is a vital part of Yemen's cultural identity, but much of it remains undocumented and unorganized. Manual classification is slow and requires expert knowledge.

This project was built to solve this. It is an automated tool that uses Deep Learning to listen to audio files and categorize them into three distinct regional styles: Adeni, Hadrami, and Lahji.

This project required a seamless handshake between a modern JavaScript frontend and a powerful Python backend. I architected a Monorepo setup to handle both concurrently.

• Frontend - A clean, responsive interface for users to upload .mp3 files and view results.

• Backend - A robust API that receives the audio, processes it, and serves the Deep Learning model.

• The Engine - A Convolutional Neural Network (CNN) trained to recognize audio patterns.

Machines cannot hear music, but they can see it. The core of our system relies on converting raw audio waves into Mel-Spectrograms, visual representations of sound frequencies over time.

We built the Python pipeline that:

1. Accepts the user's uploaded file.

2. Normalizes the audio duration.

3. Generates the Spectrogram image.

4. Feeds it into the CNN model for prediction.

Initially, our model struggled with a 60% accuracy rate due to a small dataset. Working closely with my teammate (who focused on the model architecture), we implemented Data Augmentation techniques. By adding noise, changing pitch, and stretching time in our training data, we made the model robust against poor recording quality.

This iterative tuning pushed our final accuracy to 93.84%.

While the backend was complex, I ensured the frontend remained simple. Users don't need to know about Spectrograms or CNNs. They simply upload a song and get an instant result.

• Model Serving - I learned that serving an AI model requires different considerations than a standard CRUD API, specifically regarding request timeouts and processing power.

• Cross-Language Integration - Bridging Next.js and Flask taught me how to design efficient APIs that handle file streams effectively.

• Cultural Impact - It proved that modern technology can be a powerful tool for archiving and preserving traditional art forms.
