sauw...@gmail.com - Aug 25 2008
I've got a binary file in 24 bits that I would like to convert to 16 bits and 12..
Does anyone know if there is a simple way of doing it in matlab besides using fread(fid,inf,... 
FIR Filter
sneshs - Aug 22 2008
Hello there,
I'm new in digital signal processing.
I'm going to create a linear phase filter with filter lenght N = 512 for audio signal
processing in Matlab. But I'm kind... biased and unbiased crosscorrelation

Hi,
I am trying to find the delay between two audio signals and I was using xcorr to find the delay, but the result is not satisfied. Right now I am not using any option which ... What fixed point format should i chose ? [2 Articles]

Hi all,
I am working on an Noise Adaptive Playback project to eliminate the noise from a microphone of the USB HeadSet.
My project is working ok with floating point number, now i... Zero Padding and Sliding DFT [4 Articles]
sandwich_20082001 - Aug 16 2008
Hi,
I was wondering if it is possible produce a sliding DFT, but also to
keep the effects of a zero padded spectrum.
For example, for a non zero padded signal the sliding DF... Audio fingerprinting
