For example, if an auditorium has a perceptible echo, then an initial acoustic impulse is Filter signals using the filter function. 2) Generate the echo using convolution of the input with the impulse response. Like I said in my comment, you're most probably trying to read in a multi-channel audio file, in which case wavread might most probably return an NxM array, where N is the number of samples and M is the number of channels. 12. The mathematical operation of scaling and summing these individual impulse responses to generate the tissue contrast concentration curve c(t) is known as convolution. (I discussed the concept of white noise in detail in the previous lesson entitled Convolution and Frequency Filtering in Java.) (I guess if you used a gain that was a square matrix with the same number of rows and columns as the signal has channels, then you could use that matrix to define mixing between channels.). One way to approach the deconvolution is to generate an approximation of h_3 with finite extent in the time domain, and to convolve the samples of phrase_echo.wav with that signal. Find the treasures in MATLAB Central and discover how the community can help you!
