I’ve been working on some tutorials for building vocoders in Reaktor. Be sure to watch them in HD
Part 1 looks at using bandpass filters in Reaktor core, along with “abusing” polyphony to dynamically create as many bandpass filters as we’d like.
Part 2 looks at using the core BP1 filter to compensate for gain increases as resonance increases. We also modify the resonance input to take bandwidth instead. This allows the bandwidth of the filters to adjust as we change the number of bands.
Part 3 looks at using ezFFT instead of the BP filters. It briefly talks about the Unit Circle, and FFT.
