Tuner — Complete Feature List

WhatHow much the detected pitch must change before the display updates.

EffectLower values = more reactive but jittery (display jumps on tiny vibrato). Higher values = stabler reading but slower to react when you actually drift.

When to changeLower it (2–3¢) for fine intonation work or when teaching micro-tuning. Raise it (8–10¢) for vocal vibrato or rough environments.

WhatMinimum YIN confidence required to accept a detected pitch.

EffectLower = the tuner accepts noisier/weaker signals (more false positives). Higher = only clear notes get displayed (you may see "—" on attacks or pianissimo).

When to changeRaise to 0.4–0.5 in noisy rooms. Lower to 0.2 if your instrument has a soft tone (recorder, classical guitar).

WhatInternal YIN algorithm sensitivity. Lower = more sensitive to weak periodicities.

EffectLower YIN finds the fundamental more aggressively (good for high-overtone instruments like brass and woodwinds). Higher YIN ignores weaker candidates and is more selective.

When to changeLower (0.10–0.15) for woodwinds, brass and strings. Higher (0.30+) for voice or pure-tone synthesis.

WhatHow long the last detected note remains on screen after silence.

EffectShort hold (0.1s) = display empties immediately when you stop playing. Long hold (1–2s) = the note "freezes" so you can read it after attack.

When to changeIncrease for short notes or staccato. Decrease for long sustained notes when you want to see real-time changes.

WhatHow many times per second the display refreshes.

EffectHigher = smoother needle but more CPU/battery. Lower = choppier display, less battery drain. Audio detection itself is unaffected — only the visual.

When to changeLower to 10–12 Hz for vocal work (calmer display). Raise to 30+ Hz for fast instrumental passages where you want max responsiveness.

WhatRMS audio level below which the input is considered silence.

EffectLower = the tuner picks up very quiet signals (good for soft instruments, possibly catches room noise). Higher = the tuner ignores quiet sounds and only reacts to clearly played notes.

When to changeRaise it if your tuner reacts to background hum or HVAC. Lower it for pianissimo work and soft instruments.

WhatLowest pitch the detector will look for.

EffectThe tuner ignores anything below this. Setting it to your instrument's lowest note speeds up detection and rejects sub-bass noise.

When to changeSet to ~55 Hz for cello / contrabass / tuba. ~130 Hz for violin / woodwinds. ~75 Hz for voice and guitar.

WhatHighest pitch the detector will look for.

EffectPitches above this are ignored. Lowering this avoids the detector locking onto harmonics instead of the fundamental.

When to changeLower (~1100 Hz) for voice, brass, low strings. Higher (~2400 Hz) for woodwinds. Up to 3200 Hz for violin.

WhatDelay between tapping "Record" and the actual capture starting.

EffectGives you time to put down your phone and pick up your instrument before the recording begins.

When to changeUse 5s if you need more setup time. Use None for spontaneous capture.
