The invention discloses a method and a device for processing audio data, and belongs to the technical field of computers. The method comprises the following steps of acquiring to-be-processedaudio data; determining a to-be-used target audio processing algorithm and the type information of the audio data; based on the type information of the audio data and the target audio processing algorithm, judging whether the target audio processing algorithm needs to be adjusted or not; if the target audio processing algorithm is judged to be adjusted, adjusting the target audio processing algorithm, andprocessing the audio data according to the adjusted target audio processing algorithm; if the target audio processing algorithm is judged not to be adjusted, processing the audio data based on the target audio processing algorithm. By the adoption of the method and the device, the voice communication quality can be improved.

Method and device for processing audio data

The present invention relates to the field of noise cancelling techniques. Provided are an active noise cancelling method and a headset. The active noise cancelling method comprises: upon playing an audio file, acquiring a leaked audio signal, and using a sound collection apparatus positioned at a housing of a headset to acquire external noise signals (101); removing the leaked audio signal from the external noise signals to acquire actual noise signals (102); and performing real-time noise cancelling according to the actual noise signals (103). Implementing an embodiment of the present invention enables a headset to perform active noise cancelling based on actual noise signals that reflect real scenarios, thereby enhancing play quality.

The embodiment of the invention provides a de-noising processing method and device for audio signals and electronic equipment. The de-noising method comprises the steps of acquiring an original audio signal collected through a shooting and recording device; acquiring noise characteristic parameters of an initial time period signal in the original audio signal, using the noise characteristic parameters to act as initial de-noising parameters of a first de-noising processing algorithm, and carrying out de-noising processing on the initial time period signal; and storing an effective audio signal after de-noising processing. The technical scheme provided by the embodiment of the invention, iterative de-noising processing is carried out on a signal located at the initial time period in the original audio signal, the convergence time of audio de-noising processing is shortened, and effective de-noising processing is enabled to be carried out on recorded voice signals or audio signals in video multimedia from the beginning, so that the overall voice quality of recorded information is improved, and the user experience is improved.
