Grooved: Turntable Calibration

Grooved is a simple Chrome extension that calibrates turntable speed with a single tap. Pick a song, play it aloud, and Grooved uses your device’s microphone to tell you whether your turntable is running fast, slow, or at the correct speed. It’s free, ad-free, and designed for quick, repeatable checks.

If adjustments are needed, follow your turntable’s instructions and re-check with Grooved until it’s just right. The app stays focused on one task and provides a practical way to verify turntable RPM without extra equipment.
