Embodiment Construction
[0022] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments without these specific details.
[0023] In order to illustrate the technical solutions described in this application, specific examples are used below to illustrate.
[0024] see figure 1 , is a schematic flowchart of an implementation of an automatic tuning method with a self-feedback adjustment function provided in Embodiment 1 of the present application.
[0025] Among them, step S1: obtain the audio signal of the string of the stringed instrument to be tuned, compare it with the frequency of the standard empty string, control the transmission device to adjust the peg of the string to adjust its tightness...

The invention relates to an automatic tuning method with a self-feedback adjustment function and a tuner. According to the method, after an audio signal of each to-be-tuned string of a string instrument is acquired at the first time, each string is adjusted to be at the standard idle frequency, and mechanical stress parameters corresponding to each string are recorded; after all the to-be-tuned strings complete first-time adjustment, mechanical stress of all the to-be-tuned strings is acquired again and fed back to a transmission device; and the transmission device simultaneously adjusts the strings with the mechanical stress parameters changed compared with the mechanical stress parameters obtained after first-time adjustment. Therefore, the influence of mechanical tension borne by the strings adjusted later on the adjacent strings adjusted previously is lowered to a great extent, and the tuning accuracy of the automatic tuner is guaranteed.
Description
technical field [0001] The application belongs to the technical field of audio signal processing, and in particular relates to an automatic tuning method and a tuner with a self-feedback adjustment function. Background technique [0002] Common stringed instruments such as guitars and violins need to be tuned before use. Except for experienced tuners who can tune according to experience, most users need to use a tuner to realize the tuning operation of stringed instruments. Existing manual or automatic tuners all adjust it manually after obtaining the frequency of a certain string in the stringed instrument, or adjust it automatically by the tuner. However, due to the short distance between multiple strings in a stringed instrument, when a certain string is subjected to a large tension, it will cause different degrees of mechanical tension on the adjacent strings, so that the strings adjusted later may affect the strings adjusted earlier. Good string precision. Contents o...
