Earphone audio processing method and device

The invention discloses an earphone audio processing method and device, and particularly relates to the technical field of audio processing, and the method specifically comprises the following steps: an audio acquisition module is installed in an earphone, processes the audio through the pulse width modulation technology, and transmits the processed audio to an audio feature extraction module; an audio feature extraction module obtains audio features through audio spectrum processing, phoneme processing and non-structural audio processing; an audio denoising processing module reads the audio subjected to feature extraction by the audio feature extraction module and then performs audio denoising processing to obtain a denoised audio; the denoising detection module further carries out noise reduction on the denoising to obtain a noise-reduced audio, and the audio output quality is ensured; noise data and normal audio data are divided into corresponding areas through the audio feature extraction module, a basis
