## What is Beaupré Tuner?

Born from the rigor required by artisanal harpsichord making and the maintenance of historical instruments, Beaupré Tuner puts ultra-high acoustic precision within reach of all musicians.

Whether you play the guitar, organ, violin, trumpet, clarinet, harpsichord, piano, or timpani, the intonation of your instrument and the beauty of your tone should never be compromised. Developed by passionate experts, this tool rejects the superfluous to focus on the essential: immediate responsiveness and perfect readability.

Much more than just a highly reliable tuner, Beaupré Tuner is a powerful sound spectrum analysis tool (harmonics and volumes) and a true temperament laboratory. You now have in your pocket the only tool needed to maintain your instruments and an advanced analysis console to refine your sound according to your repertoire.

Main features:
• High precision and dynamic smoothing: Optimized algorithm for fine, real-time detection. Navigate between surgical precision of 0.1 cents (precise mode) or an intelligent smoothing of 0.33 cents (smooth mode) ideal for quick pitch raising and rough tuning.
• Absolute versatility: Perfectly adapted to string, wind, keyboard, and percussion instruments, as well as voice.
• Advanced spectral analysis: The interface adapts to your device to display up to 24 simultaneous harmonics in Landscape mode. Observe their relative volumes and their natural or normalized deviation in real time. Customize the display by hiding certain harmonics according to your needs.
• Temperament laboratory: Over 90 historical temperaments included, all transposable across all 12 keys, with the ability to add your own custom configurations.
• Polyphonic generator: Emit reference frequencies and chords of up to 5 notes, modify the temperament, pitch, or transposition, and listen to the interference beats change instantly.
• 5 Display modes: Linear, circular, stroboscopic, graphic, and harmonic.
• Dynamic calculation of the inharmonicity curve (Railsback). Enabled by default in Piano mode, available for other Strings.
• Pitch detection by listening (Mic enabled) / Zen Mode (Full Screen Visualization - Mic enabled).
• Ergonomics and Accessibility: A dark, minimalist design to prevent eye strain, including a Colorblind mode (Okabe-Ito palette) for universal readability.
• Hardware support: Native support for external microphones for optimal capture.
• Pure experience: No ads. No hidden subscriptions. No intrusive banners will ruin your practice session. The complete app is yours upon purchase.
• Total respect for privacy: Audio signal processing is done strictly locally on your device. Nothing is recorded, nothing is transmitted.
• Translated into 13 languages: Français, English, Español, Italiano, Português, Deutsch, Nederlands, العربية, हिन्दी, Русский, 日本語, 中文, 한국어.

The exacting standards of acoustic professionals, now in your pocket.

The best!

### 5/5 — Recommandé

Application très complète. Multitude de tempéraments (modifiables si on veut). On peut aussi programmer son propre tempérament. Il est aussi possible de savoir comment un accord de plusieurs sons, dans un tempérament  donné, sonnera grâce à un petit clavier virtuel qui permet d'entendre plusieurs notes à la fois. Je vous recommande vivement l'Accordeur Beaupré.
