akatovo - Chebyshev Filter/Distortion
akatovo is harmonic distortion plugin based on a module in 'ppooll' - based on the +chebyshev~ module in MaxMSP.
+chebyshev~ is a distortion unit which uses various low-order chebyshev polynomials (1,2,3,4,5,7) to add even or odd harmonic distortion.
Harmonics are added using corresponding polynomial (ie. p3 adds the 3rd harmonic).
