Mechanical Keyboard Enthusiasts & Power Typists
Key Operational Impact
Engineered a native audio & haptic engine delivering switch acoustics with sub-5ms latency and binaural spatial panning.
Technology Stack & Libraries
Executive Overview
The Operational Problem
Remote workers and laptop typists miss the tactile and acoustic feedback of physical custom mechanical keyboards, while existing sound apps suffer from noticeable audio lag (>40ms) and interrupt voice calls.
The Engineered Solution
Engineered a low-latency native utility using low-level Core Audio and AVAudioEngine that maps physical keyboard coordinates to binaural stereo panning, triggers MacBook trackpad haptics, and automatically detects microphone streams to mute during calls.
- AVAudioEngine low-latency audio pipeline with pre-cached high-sample mechanical switch buffers
- Physical coordinate mapping calculating real-time binaural stereo panning based on keypress positions
- NSHapticFeedbackManager integration simulating physical switch bottom-out on MacBook trackpads
- CoreAudio stream monitoring automatically muting keyboard playback during Zoom/Teams/Discord calls
- Native multi-platform desktop release packaged for macOS (.dmg) and Windows (.exe)
- Sub-5ms global key-to-audio latency imperceptible to power typists typing over 120 WPM
- Zero audio pollution on conference calls with intelligent CoreAudio microphone detection
