A package tool for general-purpose signal denoising

This paper describes a broad package composed of signal denoising techniques in a uniform framework. The tool aims at simplifying the general tuning of the denoising techniques, by allowing complete visualization of the results and of the parameter influence on the overall performance. The methods implemented include spectral subtraction, Wiener filtering, wavelet transform, and adaptive filtering. Performance evaluation for each method can be assessed through signal-to-noise ratio, crossed correlation, and amplitude reduction criteria. Examples included illustrate the broad applicability for the package tool.
