converting speech data to suitable two dimensional data set(matrix) for transform
oncu...@hotmail.com - Apr 30 2007
hi everybody;
I want to ask how I can convert unripe speech datas to two dimensional matrix format without damaged. I want to use this two dimensional data set for wavelet transfo...

hiya,
This question centers around the difference between having an odd or even
number of taps in an FIR filter.
I'm trying to determine the coefficients of and FIR filter i... AUDIO PROCESSING, phase shifter with talk thru

I'm researching signal peak analysis at the moment with little success. I'm looking for C or MATLAB algorithms which return information about spectral (or any signal) peaks. Can an... synthesis filter in libmad
Karthika - Mar 29 2007
Helloo,
I am trying to understand the synthesis filter
bank in the LIBMAD. I could not understand in what
order the D coefficients are used to obtain the PCM
samples. Also,... Some implementable VAD (Voice Activity Detection) algorithm or Single Channel Noise-Reduction Algorithm [3 Articles]
