Abstract

The invention discloses a holographic recording technology, belongs to the field of an electronic acoustic image technology, and specifically discloses a sound recording processing method for obtaining stereoscopic simulation hearing through simulating a human hearing habit, and a correlation device. In the invention, necessary factors in the human hearing habit are simulated and supplemented through a technology device so that the purpose of enabling audio information to be stereoscopic, spacious and realistic can be achieved. The recording device is mainly composed of a head model, simulation soft ears, a pickup or a microphone. Human hearing information simulation is carried out through the head model and the simulation soft ears. Since sound is stereoscopic, spacious and realistic, the holographic recording technology can be applied to multiple fields such as films, televisions, broadcasts, music, games, live broadcasting, battle simulation and the like, fully updates and replaces existing conventional recording and sound effect technologies, and improves the sound listening effect and quality.

Description

Holographic recording technology

Technical field

The invention belongs to electronic audiovideo technical field, thereby particular content is a kind of preparation of being accustomed to sound recording, processing method and the relevant device of acquisition solid, the emulation sense of hearing by the simulating human sense of hearing.

Background technology

At present, the sound recording, processing, the playback method that on market, extensively adopt are generally Dolby Surround sound, traditional stereo.

Traditional is stereo, by placing a plurality of audio amplifiers, and according to sound bearing, a plurality of sound is reset in the audio amplifier of diverse location, to reach sound around, three-dimensional effect.

This technology has more following disadvantage.

1. need to play based on audio amplifier, multiple occasion cannot be suitable for: except applying this technology in the hall fixing, movie theatre, in general daily life, or in moving movement, cannot use this sterophonic technique.

2. sound source locus of living in angle is affected by audio amplifier number: for example Doby 5.1 is that 5 conventional audio amplifiers coordinate 1 Super Bass Loudspeaker Enclosure around sound, and this system can only be reappeared the sound in 5 orientation so.By that analogy, Doby 7.1 can reappear the sound in 7 orientation around sound.But along with the rising of audio amplifier number, be that cost of manufacture or the playback cost of audio frequency all will improve greatly, and forever cannot realize without the sound source of null field full angle and reappearing.

3. sound source distance is fixing: under audio amplifier regular situation, cannot move freely, therefore no matter whether the sound source of reappearing distance coincide with the actual conditions of sound, this distance all cannot change, fixing.The acoustic distance that sound distance is experienced playback time listener is to be all fixedly equal to audio amplifier distance.

4. sound is without the sense of reality: due to sound record and the link of resetting misfits human auditory's custom, therefore can differentiating this sound easily, listener comes from speaker playback, but not true sound in necessary being and space needs the field effect of true substitution sense poor at film, game, live broadcast etc.

5. audio-frequency information manufacturing technology and process are complicated: because alternative sounds will be assigned to different audio amplifiers, play, therefore can and record the making of audio-frequency information and bring great workload, producer need to record respectively the audio-frequency information that each audio amplifier will be play, and to each audio-frequency information adjustment editor in addition.

Main purpose of the present invention is to provide a kind of available earphone to reset, all standing of sound source angle, the amplitude adjustment arbitrarily with the need of sound source distance, the sound sense of hearing sense of reality is extremely strong, and audio-frequency information is made simple brand-new recording technology and sound pick-up outfit, to eliminate above-mentioned all technical disadvantages.

This technology can be reset by any conventional reproducers such as earphone, audio amplifiers.As required, the sound source position in audio-frequency information can be in any space angle, any space length.Sound to listen to sense very true, substitution sense is extremely strong.And related audio information can disposablely synchronously complete when recording, does not need the later stage compilation operations such as extra track shunting, greatly saves the operating time.

Summary of the invention

The mankind, listen in the systematic procedure of sound the sound wave that the final eardrum of mankind place obtains, the original sound wave that not point source of sound sends.Due to air filter action, face structure is to sound wave reflection, refraction, diffraction, and ear's structure is to sound wave reflection, refraction, diffraction, and trickle variation has occurred final sound wave.The mankind's auditory system is exactly by these variable signals, and the position of sound and distance are produced to judgement and location.

Wherein, face structure and ear's structure are the most remarkable on the impact of sound wave, its effect be collectively referred to as an associated transport effect.

Traditional record type is due to cannot recording head associated transport effect, therefore the audio-frequency information feature and the human auditory system that obtain are not inconsistent, therefore cannot carry out orientation, Distance Judgment, and the sense of reality is poor.

The present invention is owing to having the face structure similar with human body structure and ear's structure.Therefore can perfectly compensate, reappear the characteristic element in human auditory's custom.

This function mainly relies on three structure division cooperations to realize, and is respectively headform, the soft ear of emulation, microphone.

Acoustic information is pick-up or microphone institute record after the combined influence effect through headform and the soft ear of emulation.When sound reproduction, because headform and the soft ear of emulation have replaced people's ear to complete an associated transport effect, therefore the sound of uppick meets human auditory's custom, there is spatial impression, third dimension, and high fidelity.
