Abstract:

Design a new piano tuning based on sound card and LabVIEW tools. Using computer sound card to sound in the design of data collection, in the PC, LabVIEW tools as the core, the development of system operation interface and operating procedures, to receive sound data from the sound card, all kinds of algorithm processing, calculate the base frequency of sound, and calculates the sound frequency and standard of the sound frequency comparison and calculation, the relevant data and comparison results show that, and give reasonable advice and tips, so as to guide operating personnel related operations, then completes the piano tuning work. The results show that the system hardware and software design has reached the expected requirement, can be used in the piano music, also for the future design of similar piano tuning meter article puts forward a new way of thinking.

Key words: piano tuning, sound card, LabVIEW, fundamental frequency detection
