Precision Strobe Tuner vs Beaupré Tuner

Precision Strobe Tuner 2.0 A General Purpose Chromatic Musical Instrument Tuner App with special Temperament and Piano Tuning Functions. The PST combines a radial Spectrum Display with a classic Strobe Tuner and Note Dial for an ultimate visualization of pitch and tone. The Strobe Display is highly sensitive with response speed that is practically instantaneous and has long been the preferred tool for piano tuners and instrument technicians. The central Spectrum Display shows the input spectrum wrapped around the Display, with each Octave drawn in a separate color. The Note Dial is marked like a clock with the twelve notes of the Scale. All overtones of the input are shown as peaks in the Spectrum Display pointing towards their corresponding Notes. The Fundamental Indicator Tic on the Spectrum Display shows the Note of the Fundamental along the Note Dial, with the color designating the Octave. Use the Spectrum Display for coarse adjustment by tuning the Fundamental to the center of the desired Note Indicator. As the input approaches the desired Note, a Two Group pinwheel pattern becomes visible rotating in the Strobe Display. Fine tuning is accomplished by adjusting to stop rotation. The Strobe Display responds instantaneously to changes in pitch and is extremely sensitive. The outside Strobe Display works just like a classic rotating disk strobe tuner. The Two-Group pattern rotates CCW when the input is flat, and CW when sharp. When the rotation is stopped, the note is in tune. The previews show a general strobe display demonstration, an example of using the calibration function to measure the accuracy of a tuning fork and an example of guitar string tuning. The first screenshot shows the display tuning a Guitar Low E string. The Fundamental appears as an Orange peak in the Spectrum Display. This string rings bright, so the overtones are also dominant in the Display. The second screenshot shows the display for an E 440 Tuning Fork with the Calibration Dial enabled and adjusted. This Fork is 2.9 cent Flat. The PST also includes a Programmable Temperament Function with 5 user definable banks. The third screenshot shows an example of a Temperament Bank set up to a typical Piano Stretch Curve. This can also be used for tuning alternate temperaments, pedal steel guitar setups, or special guitar intonation systems. In addition, there are several Special Measurement Banks used for String Inharmonicity characterization and Piano Stretch Curve Estimation. Individual strings can be characterized by measuring the Fundamental and 2nd Harmonic separately. By careful selection of a few representative measurement points, a reasonable smooth fit Piano Stretch Curve can be generated. Any number of measurements can be used. The final screenshot shows the Input Signal Scope/Spectrum Display Page. The Detailed Operation Manual can be viewed here: www.precisionstrobe.com

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.
