Abstract

The invention is suitable for the technical field of multichannel recording, and provides a holographic sound recording method and device and terminal equipment, and the method comprises the steps: obtaining the angle of a target sound source through a microphone array in a recording process of the microphone array; and recording and storing the angle and audio data of the target sound source. According to the invention, the problem that the sound information of a continuous or moving sound source cannot be accurately recorded in the process of changing the sound along with time is solved.

Description

Technical field [0001] The invention belongs to the technical field of multi-channel recording, and in particular relates to a holographic sound recording method, device and recording equipment. Background technique [0002] At present, the application of recording technology based on microphone equipment has been very common. In many digital equipment, microphone arrays are usually used. In the prior art, stereo or multi-channel recording is performed through a microphone array, and the process of changing the amplitude of the sound over time is recorded. There is only sound intensity information, and part of the data of the sound source is lost, making the recorded audio data insufficient; in addition, In the prior art, algorithms are used to estimate the relative time difference of the sound source signal reaching the microphone array and the sound propagation speed, and estimate the sound source information, which cannot achieve accurate recording of target information.
