Thanks a lot for the info.
I've been learning to use MATLAB for the past couple days in order to get the phase information, and I have to say that it's like using a chainsaw to cut a twig... which wouldn't be a problem, except for the fact that with increasing power of an application such as matlab, comes an increasing learning curve. I'm really pulling my hair out... I understand that MATLAB is very versatile and powerful and therefore complicated to use, but I know that the phase information is not too computationally difficult to obtain. Can anyone recommend any simpler program that I can use to compute a FFT of an audio file, and provide phase information?
To be more specific: In the digital audio workstation software that I use, I can simply select an audio file, select the option "Spectrum analyzer", and a spectrum will appear. I can then move my mouse pointer over the spectrum, and an icon will trace the amplitude of the signal at the frequency position that my mouse is at. The amplitude at the current mouse position is displayed numerically above the graph.
For my purposes, the simplicity and ease of use of this analyzer is ideal.. if only it would display the phase values AND the amplitude values. Does anyone know of an application that can do it like this, or with similar ease of use?
