About Kalman Filter Noise Reduction

This application uses a 1D Kalman filter to reduce background noise in audio files. The filter employs a random-walk model to estimate the clean signal from noisy measurements, effectively suppressing consistent background noise while preserving the original audio content.

Process Noise (Q): 1e-5
Controls model trust

Measurement Noise (R): 0.25
Noise variance estimate

Processing: Sample-by-sample
Real-time compatible
