DEMO_AUDIODENOISE - Audio denoising using thresholding

Description

This demos shows how to do audio denoising using thresholding of WMDCT transform.

The signal is transformed using an orthonormal WMDCT transform followed by a thresholding. Then the signal is reconstructed and compared with the original.

Denoising

The figure shows the original signal, the noisy signal and denoised signals using hard and soft threshholding applied to the WMDCT of the noise signal.
