Best DSP for guitar effects
Hello all, I am a signal processing engineer and also a guitarist. I would like to start messing around with creating my own effects, and was wondering the best DSP to do so. Let's say that I want to build a DSP stompbox, with one 1/4" input, and one 1/4" out. I want to hook the DSP up to some knobs for par... 30 Jul 2007 13:14

help needed for Butterworth crossover response
Hi all, I implemented a butterworth crossover with the matlab (code given below). The code is working perfectly for a 4th order butterworth crossover(i.e. 24 dB/Octave). Th added response for the lowpass and high pass filters of the butterworth crossover gives 3 dB increase at the corner frequency which is ex... 25 Jul 2007 19:35

2D Phase Unwrapping Software
Best way is to get the book "Two-Dimensional Phase Unwrapping" by D.Ghiglia and M.Pritt. They have lots of different methods, so will help you choose the best method for your data. They also include C code for the methods, but I used the well-defined psudeo-code to write my own (simpler) Matlab scripts, since mat... 27 Mar 2007 09:24
