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

摘要： The invention is a control system for automatically tuning a stringed musical instrument with a capo installed, using an original calibration function or closed-loop tuning system for the instrument without the capo. The control system uses a capo scale factor which scales frequencies measured with the capo installed to what they would have been without a capo. The control system enables a musician to quickly tune an instrument after installing a capo, in a manner unlikely to be noticed by an audience.
摘要翻译： 本发明是一种控制系统，用于使用安装了Capo的弦乐器进行自动调谐，使用原始校准功能或用于仪器的闭环调谐系统而不使用capo。 控制系统使用Capo比例因子，其将使用capo测量的频率缩放到没有capo的情况下。 控制系统使音乐家能够在安装Capo后以不太可能被观众注意到的方式快速调谐乐器。

摘要： This invention provides a control system for automatically tuning a stringed musical instrument, utilizing a library of calibration functions to tune the instrument in a plurality of operating conditions without recalibration. The operating conditions can include changes in temperature and humidity, different sets of strings made with different materials and gauges, broken strings and the installation of a capo. Calibrations can also be provided for instruments of different makes and models, string lengths, body materials and actuator types. The control system is adapted for use in a stringed instrument having actuators attached to each string for changing the frequency of the string in response to a control signal. Each calibration function relates the frequency of a string to the actuator position of that string. The invention further provides an automatically tuned stringed instrument using the control system, and a method for tuning a stringed instrument.
摘要翻译： 本发明提供了一种用于自动调谐弦乐器的控制系统，利用校准功能库来在多个操作条件下调整乐器，而无需重新校准。 操作条件可以包括温度和湿度的变化，用不同的材料和量规制成的不同的弦组，破碎的绳子以及安装的卡波。 还可以为不同制造和型号，长度，主体材料和执行器类型的仪器提供校准。 控制系统适用于弦乐器，其具有连接到每个琴弦的致动器，用于响应于控制信号改变琴弦的频率。 每个校准功能将弦的频率与该字符串的执行器位置相关联。 本发明还提供了一种使用该控制系统的自动调谐弦乐器和一种用于调弦乐器的方法。

摘要： A tuning system is described for automatically tuning a musical instrument having adjustment means for changing the frequency of a musical tone produced by the instrument. The tuning system is useful with respect to a wide variety of musical instruments, e.g., stringed instruments such as guitars, harps, pianoes, etc.; horns; and other instruments. The tuning system is capable of automatically tuning all strings of a stringed instrument simultaneously.
