We propose a multi-signal fusion module to effectively . forum1529: Translation Assistance for Engineers. Click on the track (or a preset loop) you're trying to edit. The trick, however, is that an index can never be a negative value, so you cannot just say x(t-4) is x(-3:end-4). It is entirely possible that the second signal that you're convolving with is not a vector. Create a signal pulse. just wanted to ask that in the 7th line of the 1st code . The convolution should also work, just beware of the padding. See the spec definition of Convolution for more information. The function is to be called like this: output = echo_gen (input, fs, delay, amp); where input is a column vector with values between -1 and 1 representing a time series of digitized sound data.
