PST Demo

PST Demo is a versatile musical instrument tuner designed specifically for precision and accuracy. It offers a free demo version, allowing you to test its features on your specific device. The app's main functionalities include the Spectrum Display, the Note Dial, and the Strobe Display, each serving a crucial role in precise musical tuning. The Spectrum Display visualizes the input spectrum by color-coding each octave, facilitating easier identification of notes and their corresponding overtones.

Key Features and Precision Tuning

The Note Dial, akin to a clock face, is marked with the twelve musical notes, assisting in easily identifying fundamental frequencies and their positions. For optimal tuning, the Spectrum Display aids in rough adjustments while the Strobe Display provides a sophisticated visual feedback system for fine-tuning. The Strobe Display instantly reacts to pitch changes: it rotates counterclockwise if the input is flat and clockwise when sharp. Precise tuning is achieved when the strobe pattern halts its rotation. This feature is particularly helpful for various instruments, as illustrated in examples such as tuning a guitar's low E string and adjusting an E 440 tuning fork.

Advanced Functionalities

PST Demo also incorporates a Programmable Temperament Function with five user-definable banks, enabling customization for diverse musical needs like alternate temperaments and pedal steel guitar tunings. Additionally, specialized measurement banks cater to string inharmonicity analysis and piano stretch curve calculations, allowing you to characterize individual strings by measuring fundamental frequencies and harmonics separately.

Ease of Use and Compatibility

Available for Android devices running version 4.1 or newer, PST Demo ensures a seamless user experience with a comprehensive operation manual accessible within the app. Whether tuning guitars or pianos, PST Demo offers a precise, reliable solution for musicians seeking impeccable sound quality.
