The embodiment of the invention discloses an audio data processing method and device which are used for solving the problem that in the prior art, the operation that dual microphones are used for recording high-quality sounds cannot be achieved. The method is applied to a mobile terminal in which the dual microphones are arranged and comprises the steps that first dual-sound channel data from a sound source is acquired at a predetermined sound acquisition position and processed into single-sound channel data; pulse response data corresponding to a transmission path through which the sound source reaches the sound acquisition position is acquired; and the single-sound channel data is converted into second dual-sound channel data according to the pulse response data. According to the technical scheme, the problem that in the prior art, when the dual microphones are utilized to record sounds, the sounds in a left sound channel and the sounds in a right sound channel are asymmetric is solved, it is guaranteed that the recorded sounds have a stable stereophonic effect, and the quality of recording sounds by utilizing the dual-microphone is improved.
Description
technical field [0001] The present invention relates to the communication field, in particular to an audio data processing method and device. Background technique [0002] With the development of mobile phone technology, the hardware configuration of dual microphones and multiple microphones is becoming more and more popular. Under the recording conditions of dual microphones, how to perfectly utilize the hardware resources of dual microphones to create high-quality sound is a long-term exploration and optimization direction in the industry. [0003] In practical applications, due to different reasons such as the environment and hardware performance, it is often impossible to record and restore stereo sound smoothly when using dual microphones. The common situations are as follows: [0004] (1) One of the microphones was accidentally blocked or blocked by grease, dust, etc., resulting in the recorded sound being loud in one channel and quiet in the other, and the listening ...
