Here’s the latest algorithm, which has been available to supporters for a while, let out in the wild.
This is the formant filter algorithm with 10 presets. This filter allows smooth morphing between any of 16 vowels, modelled with 3 formant filters each. Expert mode allows for fine tuning of bandwidths and relative gains.
This custom algorithm is available for free to Buy Me A Coffee supporters, or you can buy this algorithm at https://www.buymeacoffee.com/godlikeprod/e/133989
