Discovery: A New Approach for Denoising and Reconstruction

Key Insight

Through the combination of attention mechanisms, positional encoding, and CNN-based reconstruction, we have effectively developed a new way to perform denoising and signal reconstruction for time-domain audio signals.

What Makes It Special?

Unlike traditional denoising methods (like spectral subtraction or Wiener filtering), our approach:

• Preserves temporal and harmonic structures (thanks to attention capturing inter-frame relations).
• Uses frame-level processing with overlap-add for smooth stitching.
• Leverages CNNs for local pattern learning and noise suppression.

This hybrid approach combines strengths from deep learning (attention, CNN) with classical signal processing techniques (framing, overlap-add).

Why This is Important

Traditional denoising methods often distort phase or introduce musical noise.

• Our approach keeps the signal-to-noise ratio (SNR) high, while preserving natural tonal quality.
• This is particularly useful in musical note processing (like MiddleC), speech enhancement, or even bio-signal reconstruction.
