Embodiment Construction
[0065] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0066] figure 1 It is a flowchart of an audio signal processing method based on electronic tone control in an embodiment of the present invention. Such as figure 1 As shown, the method is implemented by an analog signal input terminal, an audio codec, an audio DSP, and an analog signal output terminal, including:
[0067] Step S101, the analog signal input terminal receives the input analog signal, and sends the input analog signal from the analog signal input terminal to the audio codec;
[0068] Step S102, the audio codec converts the input analog signal received from the analog signal input terminal into an input digital signal, and sends the input digital sign...

The invention discloses an audio signal processing method and system based on electric sound tone control. The processing method comprises the steps that: an analog signal input end receives an input analog signal and sends the input analog signal to an audio encoding and decoding device from the analog signal input end; the audio encoding and decoding device converts the input analog signal received from the analog signal input end into an input digital signal and sends the input digital signal to an audio DSP; after receiving the input digital signal, the audio DSP identifies frequency components in the input digital signal, adjusts the input digital signal according to the frequency components in the digital signal, expected tone and a preset adjustment method, obtaining an output digital signal, and sends the output digital signal to the audio encoding and decoding device; the audio encoding and decoding device converts the output digital signal received from the audio DSP into an output analog signal and sends the output analog signal to an analog signal output end; and the analog signal output end carries out output according to the received output analog signal.
Description
technical field [0001] The invention relates to the field of sound processing, in particular to an audio signal processing method and system based on electronic tone control. Background technique [0002] At present, the popularity of electronic audio signals has made the processing of electronic audio signals have a wide range of demands, and among them, it has become a relatively urgent part of audio signal processing to adjust the audio signal according to the required electronic tone. kind of demand. Although there are some devices and software to process the audio signal, basically only the tone of the audio signal can be calculated and the audio signal cannot be adjusted according to the desired tone. Therefore, there is a need for a method and system capable of processing audio signals according to the electronic tone. Contents of the invention [0003] To solve the above problems, the present invention provides an audio signal processing method and system based o...
