Engineered for Purists

Designed with Apple Craftsmanship.

Every keystroke is an acoustic event. ThockBar synthesizes the nuanced physical behavior of mechanical switches with zero latency.

True Up/Down Keystroke Engine

Real mechanical keyboards don’t make a single click. They produce distinct downstroke bottom-out impacts and gentle upstroke switch reset clicks. ThockBar independently models both acoustic phases in real time.

Interactive 2D Tone Pad

Seamlessly morph between deep, buttery "thock" and sharp, snappy "clack" across two axes of parametric audio filtering.

Ultra-Low Latency & Native Swift Architecture

Built natively with Swift and Apple CoreAudio. Keystrokes are intercepted through a zero-overhead local event tap and dispatched instantly in under 5 milliseconds—without taxing your CPU or draining battery.

< 4.2 milliseconds dispatch latency
0.0% CPU at Idle

100% Offline & Private by Design.

Zero keylogging, zero data transmission. ThockBar requires macOS Accessibility permissions solely to trigger real-time audio playback on your local machine. Nothing is ever recorded, stored, or sent to external servers.
