From: gökan vural on 6 Feb 2010 20:57 Hi Wayne, i've used spectogram and obtained 2D graphics.. What i need is a 3D one, with time, amplitude and frequency.. ie I want to take 40 samples of FT from a song, with a constant window T.. Then, via combaning the 40 FT graphic, i'm gonna have a 3D graphic.. Near freq and ampl, time is also placed.. Regards

I'm hoping that if I read these posts I will be inspired to install matlab again. I handed in my report (on speech analysis) to the lecturer at end of 2005, and haven't used matlab since.
