I've been working on a package of timbre classification externals for Pd. This is a refinement and expansion on the earlier cepstrum~, mfcc~ and bfcc~ externs. Now the classifier is separated from the feature generators, and several non-cepstral features are available. With these tools you can measure spectral centroid, flatness, flux, rolloff, brightness, etc. in real time and pack lists of features together for classification purposes. A hierarchical clustering algorithm can be applied to given training data, making all steps of the process much more streamlined and easy to use. See the [research] page for more information.



The second generation of ludbots is ready. This brings the total up to 32 units, meaning that some interesting spatialization and ensemble coordination will be possible soon.
