Pitchli

Fast, stable chromatic tuning with a clean visual meter for guitar, bass, and lower-register instruments.

Pitchli is a high-accuracy chromatic tuner built for guitar, bass, and lower-register instruments.

Use it as a standalone tuner with your device microphone, or load it as an AUv3 effect inside compatible music apps.

Features:

• Accurate real-time pitch detection tuned for bass notes below guitar low E through high guitar ranges
• Smooth horizontal cents meter with clear flat/in-tune/sharp feedback
• Adjustable reference pitch (A4 = 420-460 Hz)
• Low-noise idle behavior that avoids unstable ghost readings
• Audio Unit v3 extension support for compatible host apps

Standalone mode:

• Uses microphone input for direct instrument tuning
• AUv3 host-specific controls (such as MIDI routing behavior) are disabled

Notes:

• Microphone permission is required for standalone tuning.
• For AUv3 use, load Pitchli in a compatible host app.
