Microphone-based pitch detection for tuning.
The Online Guitar Tuner is a precise, browser-based chromatic tuner that helps you tune your guitar, ukulele, or bass using your device's microphone. It visualizes the pitch of the sound you play in real-time, showing you exactly how close you are to the target note. Whether you use standard EADGBE tuning or an alternate tuning, this tool detects the frequency and guides you to the perfect pitch. It works on both desktop and mobile devices without requiring any app installation. The interface is designed to be simple and responsive, filtering out background noise to focus on your instrument's sound.
