What makes a convolution kernel separable? Ho开发者_StackOverfloww would I be able to tell what those separable parts were in order to do two 1D convolutions instead of a 2D convolution>
I\'m currently working on this project that implies some DSP skills. I must extract the audio from a movie and then, by analyzing it, I must determine when someone speaks or not, more like an voice ac
I am trying to build a DBPSK demodulator using Simulink and Xilinx blockset. I calculate the Phase Difference of the Successive samples like this :
I found in one research on VP8 decoding phrase \"6-tap filter in开发者_开发百科 any case will be a 6-tap filter, and the difference is usually only in the coefficients\". So what is 6-tap filter, how
I am using 开发者_JAVA技巧the NAudio DLL and I am looking for example code for pitch shifting sound.There is an example of using NAudio for pitch shifting in the open source Skype Voice Changer projec
SHORT AND SIMPLE: What are the steps that are involved to get an MFCC from an FFT. DETAILED: I\'m working on a drum application to classify sounds. Its a matching application for the iPhone with the o
Hi all I am using the fftw C libraries to compute the frequency spectrum for some signal processing applications on embedded systems. However, in my project I have run into a slight hinderence.
How does the DCT (Discrete Cosine Transform) help to compress sound (or any wave-like data)? According to the DCT transform there are N input values and N output values as a result. Where is the compr
Okay, this a bit of maths and DSP question. Let us say I have 20,000 samples which I want to resample at a different pitch. Twice the normal rate for example. Using an Interpolate cubic method found
I have been looking into how to convert my digital data into analog. So, I have a two column ASCII data file (x: time, y=voltage amplitude) which I would like to convert into an analog signal (varyi
