Speech Denoising Based on Wavelet Packet Decomposition

Speech denoising using wavelet packet decomposition with threshold estimation via entropy spectral probability density function to remove real-world environmental noise. The implementation involves signal decomposition, entropy-based threshold calculation, and coefficient processing for noise removal.

Dual-Channel Speech Enhancement Algorithm

Dual-channel speech enhancement algorithm for environmental noise cancellation, implementing normalized adaptive methods to achieve 10dB noise reduction while maintaining high speech intelligibility.
