This plugin is an analog tape emulation algorithm by Jatin Chowdhury, a mini version of the mindblowing AnalogTapeModel vst plugin by the same. For a deep dive, see Chowdhury's paper on analog tape modelling. This smaller version is mostly useful as a tape saturation/distortion.
The plugin's guts feature variable oversampling and anti aliasing filters to achieve high quality distortion.
Tape bias. 0.0 to 1.0.
Tape saturation. 0.0 to 1.0 but may be pushed harder.
Tape drive. 0.0 to 1.0 but may be pushed harder.
Set amount of oversampling
0 = No oversampling, 1 = x2, 2 = x4, 3 = x8, 4 = x16
Change the mode (solver type) of the tape algorithm: 0 = RK2 (2nd order Runge Kutta) 1 = RK4 (4th order Runge Kutta) 2 = NR4 (4-iteration Newton Raphson) 3 = NR8 (8-iteration Newton Raphson)
The Runge-Kutta solvers are computationally cheaper, but somewhat less accurate than the Newton-Raphson solvers. Similarly, the higher-order solvers will be more accurate, but will also consume more compute resources.
