    Using Neural Networks to model the response of a loudspeaker HELP!!!!

    by the way, p1 p2 and p3 were very simple 10 value matrices created with rand, so i dont understand why the NN are having trouble. k

    Using Neural Networks to model the response of a loudspeaker HELP!!!!

    yes i think that you are right. I have tried creating 3 random matrices, p1, p2, p3, and filtering with a simple FIR Filter, with an impulse response known to me. This gave me f1, f2, f3 respectively. Then I trained a NN with p1 and f1. Then when you simulate the NN with p1 you get something...

    Using Neural Networks to model the response of a loudspeaker HELP!!!!

    Hi thanks for your response I appreciate it! I do have the impulse response of the microphone/loudspeaker pair already which I obtained from deconvolving the played sound source from the recorded one; I did this with a separate piece of software which uses linear techniques to do so. I want to...

    Using Neural Networks to model the response of a loudspeaker HELP!!!!

    Hi there, I am currently working on a problem using MATLAB and have come across some problems that I hope someone out there will be able to help solve. Basically I am sending noise to a loudspeaker and recording that noise through a microphone. Then I want to train a NN in matlab ( I...
