AntiVuvuzelaFilter
🎵 Noise filter for clear audio 🎙️
Anti-Vuvuzela Filter is an open-source project dedicated to second-order analog filters and beyond. This project was initially developed to design an “anti-vuvuzela” filter, aiming to attenuate the distinctive and persistent sound of vuvuzelas while preserving the clarity of commentators’ voices during the 2010 FIFA World Cup.
🎯 Purpose
- 🔇 Targeted Noise Reduction: Specifically designed to attenuate vuvuzela noise while maintaining the intelligibility of speech.
- 🎚 Second-Order Analog Filtering: Utilizing advanced filtering techniques for efficient noise cancellation.
- 🛠️ Open-source and Customizable: Modify and adapt the design for other audio filtering applications.
