Voice Enhancer & Recorder (Python 3.14 Compatible)

Overview

This project is a fully functional voice recording and enhancement application written in Python.
It records audio in real time, applies noise reduction, normalization, high-pass filtering, and dynamic compression — then saves the processed result as a high-quality WAV file.

Unlike older Python versions, this version is fully compatible with Python 3.14, avoiding deprecated modules and using a modern signal-processing pipeline.
