Audio has been used to generally describe devices in the audio range and their role in relation to sound. All sounds that a human being can hear are referred to as audio, which may include noise, etc. After the sound is recorded, either the speech, singing, or musical instruments can be processed through digital music software or made into a CD, where all the sound is unchanged since a CD is originally a type of audio file. And audio is simply sound stored in the computer. If a computer is provided with a corresponding audio card, namely a sound card which is often called, all sounds can be recorded, and acoustic characteristics of the sounds, such as sound level and the like, can be stored in a hard disk file of the computer.
The popularity of electronic audio signals at present makes the processing of electronic audio signals have a wide demand, and among them, it is urgent to perform up-scaling, down-scaling, etc. on audio signals according to the required electrical tone. Although some devices and software process audio signals, basically only the key of the audio signals can be calculated, and the audio signals cannot be adjusted according to the expected key.
There is therefore a need for a system for tuning the pitch of an electrical tone based on song identification.
The invention discloses an audio signal processing method and system based on electric tone pitch control, which comprises the following steps: the analog signal input end receives an input analog signal and sends the input analog signal to the audio codec from the analog signal input end; the audio codec converts an input analog signal received from an analog signal input end into an input digital signal and sends the input digital signal to the audio DSP; after receiving the input digital signal, the audio DSP identifies the frequency component in the input digital signal, adjusts the input digital signal according to the frequency component in the digital signal, an expected basic tone and a preset adjusting method to obtain an output digital signal, and sends the output digital signal to an audio codec; the audio codec converts an 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; the analog signal output end outputs the received output analog signal. But its existence still remains incapable of adjusting the pitch of the tone based on song identification.
An effective solution to the problems in the related art has not been proposed yet.
