Noise Cancellation Prototype

Testing Controls:

Input Level

Output Level

How to use:

1. Click "Check Permissions" to verify microphone access
2. Click "Test Audio Context" to test audio output
3. Click "Start Noise Cancellation" to begin
4. Use "Enable Direct Monitoring" to hear raw microphone input (helps verify input)
5. Adjust frequency and phase controls to target specific noise

Tips for best results:

• Start with low gain (30% or less) to avoid feedback
• Position the phone away from speakers if possible
• Focus on specific frequency ranges rather than trying to cancel all noise
• Try different delay settings to account for processing latency
• Use headphones for initial testing to verify the system works

⚠️ Note: This is an experimental prototype and results may vary based on your device and environment.
