Zusammenfassung: | 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 |
