Abstract
The invention discloses a musical instrument precision detecting method. The method comprises the following steps that (1), a standard tone of a musical instrument is set, wherein the standard tone comprises the time-domain characteristic, the spectral characteristic and a standard tone frequency; (2), harmonic tones of the musical instrument to be detected are collected and converted to the time-domain characteristic, the spectral characteristic and the standard tone frequency of the musical instrument to be detected through a calculating and converting unit; (3), the standard tone and the collected harmonic tones of the musical instrument to be detected are compared, and results are output. The musical instrument precision detecting method has the advantages of being high in measuring precision, convenient to use, visual and accurate, and capable of being applied to pitch setting devices, tuners, metronomes and the like for various musical instruments.
Description
Technical field
The present invention relates to filter field, specifically, be related specifically to a kind of musical instrument accuracy checking method.
Background technology
Chinese musical instruments manufacturing has basically formed comparatively complete industrial production system, substantially all large kind musical instruments in the world can be processed, covering extensive fields, kind is numerous, different classes of more than 1200 models such as nearly piano, violin, western wind instrument, specification more than 30,000, the large kind musical instrument such as piano.Its product has formed Virtual production general layout, and the main piano parts specialty such as piano iron plate, soundboard, hammered string instrument, shell processing factory starts to form scale.
Summary of the invention
The object of the invention is to for deficiency of the prior art, provide a kind of musical instrument accuracy checking method, to solve the problem.
Technical matters solved by the invention can realize by the following technical solutions:
Musical instrument accuracy checking method, comprises the steps:
1) set the standard pronunciation of musical instrument, described standard pronunciation comprises time domain specification, spectral characteristic and standard pronunciation frequency;
2) gather each humorous Boeing of musical instrument to be detected, and each humorous Boeing is converted to the time domain specification of musical instrument to be detected, spectral characteristic and standard pronunciation frequency respectively by calculating converting unit;
3) each humorous Boeing of standard pronunciation with the musical instrument to be detected collected is compared, and Output rusults.
Preferably, the times of collection of the humorous Boeing of described musical instrument to be detected is 8 ~ 12 times.
Preferably, the described humorous Boeing collected for 3 ~ 4 times is set to one group.
Compared with prior art, beneficial effect of the present invention is as follows:
It is high, easy to use, intuitively accurate that the present invention has measuring accuracy, can be used for the pitching instrument of various musical instrument, organ stop, metronome etc.
