I am trying to build my first external and I was looking for some example that would use fft and windowing. I am trying to build something similar to bonk but using a different approach and some machine learning. I've looked at sigmund and hanning for windowing and trying to figure out. moog's and katja's externals were very helpful as well in understanding.

is there any other external that could give me some hints?

Hello dio_333,

William Brent has interesting classes. [bark~] is an alternative for [bonk~], without learning but better readable code. [timbreID] is an advanced vowel identificator with learning. Binaries for OSX and Windows available, I don't know how easy it is to build.

thank you!
I find this very helpful and there is also some learning involved in another set of externals dealing with timbre spaces, on the same page(using knn as I wanted to!)

also the fftease externals do internal transformation and windowing while blocksize is set from the outside by a [block~] object.
