Chow Tape is a series of audio effects based on a physical model of a reel-to-reel tape recorder.
Tape Saturation is a saturation effect achieved through a physics-based model of a reel-to-reel tape machine. The effect uses a discretization of the Jiles-Atherton equation to emulate the magnetic hysteresis process which is results in the magnetization of the domains in the tape itself. The end result is a smooth and dynamic saturation effect, which can be under-biased or over-biased just like a real tape machine.
The effect also includes pre- and post-emphasis filters similar to those often used by reel-to-reel tape machines, which can be controlled by the "Tone" knob, as well as filters that emulate the loss of certain frequency content in the signal, depending on the "Speed" of the tape used for recording.
Tape Modulation is a modulation effect that emulates the "Wow" and "Flutter" effects often present in analog tape recordings due to inconsistencies in the tape speed during recording or playback. While tape machines were built with the intention of reducing wow and flutter artifacts, this effect accentuates them for musical effect.
The Flutter effect is modelled directly after the timing inconsistencies in my own tape recorder, and has controls for the "Rate" and "Depth" of the effect.
The Wow effect contains similar "Rate" and "Depth" controls, as well as controls for "Variance" and "Drift", which can be used to achieve a more random and dynamic effect.
