Settings
Overview
Use the Settings tab to customize audio, analysis and display behaviour.
AUDIO
Source
This setting selects the audio source for the analysis. Available options are:
- Microphone: for live audio,
- Song Library: for recorded audio,
- A440 Tone: a test tone, and
- Complex Tone: a test tone with 10 harmonics.
- Select the Song Library source.
- Return to any one of the analysis views.
- Tap anywhere in the song title area, then select a song.
ANALYSIS
Mode
This setting controls how the app interprets the audio spectrum. Available options are:
- Spectral: for random sounds and classic sound analysis, and
- Perceptual: for musical sounds and polyphonic pitch analysis
Tuning
This setting controls app's tuning reference. For best performance, the tuning reference should match that of the sound source. The range for the tuning reference is 429Hz to 451Hz, namely A440 ±44 cents.
The setting can be adjusted in two ways:
The setting can be adjusted in two ways:
- Via the Settings page, or
- Via the Tuning view.
Tempo
This setting represents the expected rate of change of the sound source. The default setting works well for most sound sources. Available options are:
- Slow: for steady sounds and slow music (under 90BPM),
- Medium: for most sounds and music (90 to 150BPM), and
- Fast: for fast sounds and music (over 150BPM).
Compression
This setting controls the relative importance of weaker partials in the analysis. The value range is 0% to 100%. The default setting works well for most sound sources.
A higher value boosts weaker partials (as well as their relative brightness in the Spectrum view), while a lower value tends to leave them unchanged.

Sensitivity
This setting controls the relative number of partials included in the analysis. The value range is 0% to 100%. The default setting works well for most sound sources.
A higher value boosts the number of partials, while a lower value limits the number. More partials do not necessarily yield better results; quality matters more than quantity.

DISPLAY
Top Note
This setting selects the pitch class that appears in the twelve o'clock position of the Tuning and Notes views. Any one of 12 semitones can be selected. The default choice is A.
Accidentals
This setting selects the accidental label used to identify pitch classes. The options are:
- Sharp (♯)
- Flat (♭)
Auto-Lock
This switch controls the auto-lock behaviour of the display while the app is in the foreground. The default setting is on.
If the switch is on, the normal auto-lock behaviour of the display applies, as specified by the global Auto-Lock setting of the device. If the switch is off, auto-lock is disabled, thus preventing display interruptions during audio analysis.
