Hi Guys, Another year has almost passed so I thought it was time to release another technical paper!
It's a dynamic smoothing algorithm that can do things like this: http://cytomic.com/files/dsp/dynamic-smoothing.png I came up with the idea a few years ago when I needed a way to de-noise and de-step the cutoff of a self oscillating filter when mapped to a midi controller. It uses a dynamic 2 pole multimode filter. The basic idea is to use a filter's bandpass output to modulate its own cutoff frequency. The basic version takes 6+-, 3* and one absolute value, details here: http://cytomic.com/files/dsp/DynamicSmoothing.pdf Enjoy, and have a happy holidays everyone :) Cheers, Andrew _______________________________________________ dupswapdrop: music-dsp mailing list music-dsp@music.columbia.edu https://lists.columbia.edu/mailman/listinfo/music-dsp
