A three-model 3D sound effect generation method and its acquisition method

Abstract

The invention relates to a three-model 3D sound effect generating method and an obtaining method thereof, which are used for outputting sound information according to corresponding power amplifies ofa sound source in a main body; each sound source corresponds to a sound source position and a first sound source content; the first sound source content comprises sound source data at each corresponding moment; the main body is provided with a plurality of preset positios and postures; each preset position and posture has the first position and posture point corresponding to the left ear of the main body and a second position and posture point corresponding to the right ear of the main body. Firstly, compared with the prior art needing the real-time complicated calculation, the method has theadvantages that the obtaining on the 3D sound effect is realized by using a retrieval method; higher simplicity and greater convenience can be realized; the response efficiency is greatly improved.

Description

technical field [0001] The present invention relates to a 3D sound effect system, and more specifically, to a three-model 3D sound effect generation system and an acquisition method thereof. Background technique [0002] The biggest difference between A3D technology and traditional methods is that it can use only a set of speakers or earphones to produce realistic stereo sound effects and locate sound sources in different positions around the user. This ability to track sound sources is called positional sound effects, and it uses the HRTF function at that time to achieve this magical effect. [0003] The full name of the so-called HRTF is Head-Related Transfer Function (Head-Related Transfer Function), which is how the human ear monitors and distinguishes the source of sound in a three-dimensional space. To put it simply, the sound waves will be transmitted to your ears with a gap of a few millionths of a second, and our brain can distinguish those subtle differences, use ...

Problems solved by technology

[0005] At present, with the popularization and application of 3D glasses technology, it is possible to sample the pose of the human head, and the original 3D sound effect algorithm first needs to determine the sound source, and then according to the position of the sound source and the content of the sound source Perform conversion according to the position of the subject, and then convert according to the pose of the subject to obtain the output sound data of different power amplifier units. However, due to the large amount of calculation, it is very prone to time delay and affects the user experience.
