Problems solved by technology

In addition to audio recording and playback, there is no ability to capture, playback and control the sound field in video recording and playback such as traditional mobile phones, resulting in poor overall video experience
In the fields of video surveillance, online education, network audio and video communication, etc., either there is no audio capability at all, some are simple mono audio, and some are ordinary stereo. In short, the auditory experience is far from meeting the immersive needs

Abstract

The invention relates to a holographic audio device and a control method. A microphone unit collects a three-dimensional sound field signal, a collected signal processing module is used for processing the collected signal and converting the collected signal into a digital signal, the digital signal is input into a holographic sound field signal processing unit, the holographic sound field signal processing unit processes a sound field signal, and the processed signal is transmitted to a host through a network after source coding compression. The host transmits the signal to the holographic audio device through the network, the signal is input into the holographic sound field signal processing unit after source decoding, the holographic sound field signal processing unit outputs the signal to a playback signal processing module, and audio playback is performed through an audio playback unit.

Description

technical field [0001] The invention relates to a holographic audio device and a control method. Background technique [0002] Traditional recording methods include single microphone recording, stereo recording (AB, XY, MS, ORTF). Single-mic recording is the easiest, but the sound field is also the most monotonous; the original intention of stereo recording is to create a richer stereo field, and there are various ways in microphone configuration, all of which try to simulate the perception characteristics of human ears to sound , such as delay, amplitude difference, phase, etc. However, it is difficult to simulate the real human ear perception only by the placement of the microphone. Simulated human head recording can realize the realistic representation of immersive three-dimensional sound field, but it is mainly used in some professional laboratories as a test tool. For a wide range of audio and video recording, it is extremely inconvenient to use, and it is also extreme...
