Hi Gunter Geiger, pd devs,

I have recently begun to write an external for SMS synthesis, by basically porting the command line tool Xavier Serra wrote within the original SMS code (found at http://www.iua.upf.es/~sms/software/Old-SMS-for-NextStep.zip). I was talking to Xavier about this and he mentioned that you almost got an external working with sms.. Before I did too much work, I figured I would ask to see what types of problems you ran into, or if you have any suggestions.

Hi,

I have part of the SMS process implemented, but not as a single external but as a collection of externals for generation of windows, peak detection, interpolation, FFT resynthesis. These are glued together with standard pd objects. I sort of got stuck trying to figure out how to use the extracted data in a meaningful way inside pd.

So, after all,it might be a better approach to do it as a single external and program your transformations in C/C++. So maybe the best bet would be to have a base SMS analysis/synthesis engine and do an external for each effect that you want to implement with it.

Gunter

I'm also sending this to the pd-dev list to see if others have suggestions. I figure that I will start by doing just a port of the command line tool, and then later add in features for seeking through frames at any speed and direction, visually manipulating the data, and other fun things. But I would like to know what others think.

regards, rich
