A kind of ear effect 3D recording ring

Abstract

The invention relates to an auditory-effect 3D recording ring. The auditory-effect 3D recording ring comprises a wearing lifting handle, two recording ring bodies and recording control modules, wherein the recording ring bodies are symmetrically installed at the two ends of the wearing lifting handle. The auditory-effect 3D recording ring is characterized in that each recording ring body is an annular framework, the middle of each annular framework is hollowed, a plurality of microphones are installed on the inner side of each annular framework in a hidden mode, and the microphones are connected with the corresponding recording control modules and are controlled by the recording control modules to carry out 3D synchronous recording. According to the auditory-effect 3D recording ring, the effect of interference of auricles and the head in a sound field is fully utilized, a recorded array sound signal includes space information of the sound field, when an auditory-effect 3D sound listening ring is used for playing sounds, a listener can obtain a remarkable real 3D sound feeling, and the problems that the sense of space of signals obtained through ordinary binaural internal recording and signals obtained through professional manual head recording is not obvious, and earphones need to be worn in the ear canals of a person to carry out recording in an existing double-sound-channel 3D recording process are solved; the auditory-effect 3D recording ring is used in cooperation with the auditory-effect 3D sound listening ring, and sensitivity to the difference of different heads is much lower than that of a traditional ear canal internal recording mode or a manual head recording mode or other recording modes.

Description

Technical field [0001] The invention belongs to the technical field of 3D sound processing, in particular to an ear effect 3D recording ring. Background technique [0002] At present, two-channel headphones are increasingly pursuing 3D effects, and the use of two-channel headphones for 3D sound field recording technology is gradually being developed. For example, the 32-element spherical array with a diameter of 80 mm by Mhacoustics of the United States is a spatial 3D sound field recording device. After VBAP, HOA, WFS and other algorithms are transformed, various forms of 3D sound field can be generated. It is still unable to produce true 3D sound effects for hearing during playback. The 32-element circular array patent of Delft University of Technology in the Netherlands, "Circular microphonearrayformultichannelaudiorecording", WO / 2004 / 084577, EP1606970 is also a 3D sound field recording device. When the recorded signal is directly played with headphones, the auditory sense ca...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide an ear effect 3D recording ring, which solves the problem that the existing binaural recording and professional artificial head recording signal have no obvious sense of space, and the existing two-channel 3D recording needs to The problem of recording with headphones installed in the human ear canal
