Description

Broadband audio denoisers are based in speech processing, most of them not suitable for music type files. Speech processing type estimates broadband noise during speech pause periods, or apply noise measure to whole file without changes in it's estimation. Music needs another type of noise estimation, an this application does this. New algorithm is implemented for noise estimation, and an Ephraim-Malah log-MMSE is used instead conventional spectral subtraction rule, resulting in more musical noise reduction. Presented application provides good quality with high noise reduction, easy manage, using Fast Fourier Transform (using FFTW library):

• Music noise reduction
• High quality results
• WAV, OGG, MP3, WMA audio supported
• Audio and noise spectrum visualization while file is being played
• Added control to improve high frequency harmonics
• Now the FFT is computed via FFTW library to improve performance
• Windows 7 compatible
