Tuner Module - User Manual

Introduction

The Tuner module provides a chromatic tuner that uses your device's microphone to detect pitch. You can tune to a standard reference (A4 = 440 Hz), choose sharp or flat notation, and focus on specific instruments.

Getting Started

Accessing the Tuner

Click "Tuner" in the main menu (under "Tools")
The full-screen tuner opens
No band selection required - available to all logged-in users

Permissions

The tuner needs microphone access. When you start listening, the browser will ask for permission. You may need to tap or click once (user gesture) before the microphone can be used.

Using the Tuner

Starting and Stopping

Start – Click the microphone button to start listening. Allow microphone access when prompted.
Stop – Click the microphone button again to stop.
Status – The message below the button shows "Listening...", "Requesting microphone access...", or an error message.

Reading the Display

Note – The detected note (e.g. A, B, C#) is shown large. The small label above can show the instrument preset name.
Cents – How many cents sharp (+) or flat (-) you are. 0 means in tune.
Meter – The needle moves left (flat) or right (sharp). Center is in tune.
Frequency – The detected frequency in Hz.

Settings (gear icon)

Reference Frequency (A4) – Standard is 440 Hz. Use +/- or type a value (400–500) if you use a different standard.
Instrument – Choose an instrument to show only relevant notes (e.g. guitar strings), or "Tuner (All notes)" for chromatic.
Notation – Sharp (#) or flat (♭) for note names.

Close

Use the X button (top right) to close the tuner and go back.

Tips

Quiet environment – Reduce background noise for better detection.
Single note – Play one note at a time for accurate reading.
User gesture – If the tuner does not start, tap or click once on the page, then press the microphone button again.
Microphone in use – If another app is using the microphone, stop it or close the tuner and try again.

Troubleshooting

No sound / Microphone not working

Allow microphone permission in the browser (or device settings).
Make sure no other app is using the microphone.
Try clicking the microphone button again after a user gesture (tap/click).

Wrong note or unstable

Play a clear, sustained note.
Reduce background noise.
Check that the correct instrument preset is selected if you are tuning a specific instrument.
