A browser-based pitch detection demo app built on the Web Audio API, using a realtime autocorrelation algorithm to detect the pitch of monophonic audio input. It works with live microphone input, demo audio, or an oscillator, and is useful for tasks like instrument tuning.

Use cases

• detect pitch of live microphone input in the browser
• tune a guitar or other monophonic instrument
• experiment with autocorrelation-based pitch detection
• test live audio input with the Web Audio API
• analyze pitch of whistling or simple waveforms
• display detected frequency in Hz and cents deviation

When to choose

• you need a simple, MIT-licensed browser demo of realtime pitch detection
• you want to learn how autocorrelation pitch detection works in JavaScript
• you need a quick tuner for monophonic sources like whistling or guitar

When to avoid

• you need robust pitch detection for polyphonic audio or strong harmonics
• you need a production-grade, well-maintained library rather than a demo app
• you need pitch detection outside the browser environment
