This invention is a display system for measuring and displaying, individually or simultaneously, the frequencies contained in a musical sound. A transducer (21) coupled to the sound source produces an electrical signal representing the musical sound. The system receives the signal and separates (51, 52 and 56) and measures (57) the frequencies of the individual tones comprising the sound. The measured frequency values are displayed (72) as the frequencies themselves or as deviations from target frequencies. The system can utilize a local or remote transducer with the display system.

Cette invention concerne un système d'affichage permettant de mesurer et d'afficher, individuellement ou simultanément, les fréquences constituant un son musical. Un transducteur (21) couplé à une source sonore produit un signal électrique représentant le son musical. Le système va recevoir ce signal et séparer (51, 52, 56) puis mesurer (57) les fréquences des tonalités individuelles composant le son. Les valeurs des fréquences mesurées sont affichées (72) sous forme des fréquences elles-mêmes, ou sous forme de déviations par rapport aux fréquences cibles. Ce système peut faire appel à un transducteur local ou à distance fonctionnant avec ledit système d'affichage.
