Question about cross-spectrum and convolution [2 Articles]
Ze Ji - Dec 19 2005
Hi, I have a question regarding the concept of cross-spectrum, which is defined as the Fourier transform of convolution between two signals X and Y: FT(X*Y)
Isn't it the ...

raja...@yahoo.com - Dec 16 2005
Hi,
I'm working on implementing Trick Modes (fast forward, rewind etc) in MP3. In this context, I need to play audio at higher speeds (2x, 4x). Skipping audio samples distorts ... audio interpolation [2 Articles]

Hi,
Please, can anybody tell how can I remove the hiss noise from the interpolated audio signal?
Here, I am simulating the interpolation using c-program and scilab code. I Thoug... interpolation of audio signal
