HoRNet Cassette644 is an audio plugin crafted to replicate the warm and saturated sound of vintage cassette tape recordings. Its design captures the character of a classic 4-track cassette recorder, bringing authentic analog warmth to digital productions. Users can emulate the sonic textures of various cassette types, including Normal, Chrome, and Metal tapes, while selecting between slow and fast tape speeds to explore different playback characteristics.

The plugin incorporates a flexible three-band semi-parametric equalizer that enables detailed tonal shaping with adjustable high shelf, mid-band, and low shelf controls. This EQ can be toggled independently, allowing seamless blending with the cassette emulation. An authentic hiss noise generator adds a realistic layer of tape noise, which can also be switched on or off. Additionally, flexible signal routing options let users place the EQ before or after the cassette section, providing creative control over the processing chain.

HoRNet Cassette644 features high-quality audio processing with up to 4x oversampling, preserving clarity while delivering analog-style coloration. A unique linking function synchronizes settings across multiple plugin instances, ensuring consistent sound in multitrack projects. The interface adapts to system light or dark modes and supports Apple Silicon natively, compatible with macOS and Windows systems. With support for Audio Units, VST, VST3, and AAX formats, this plugin integrates smoothly into a wide range of digital audio workstations.
