Abstract

The utility model discloses a three-dimensional (3D) airy voice, and belongs to the technical field of computer music manufacturing. A 2.0 two-channel stereo can be made into a surround sound field of a Dolby logic positioning system, namely a 2.0 two-channel stereo audio file is analyzed and technically split into a plurality of channel logic surround sound positioning audios, and then a multi-channel logic surround sound audio file is technically analyzed and combined to form the 2.0 two-channel stereo audio file, so that people can hear a multi-channel (such as 5.1, 6.1, 7.1 and the like) logic positioning surround sound field through the common two-channel stereo headset or an audio file played by a loudspeaker. The '3D airy voice' is particularly suitable for a multimedia computer, an automobile loudspeaker, a personal stereo, a family cinema and a cinema and can be applied to a video tape recorder, a laser disc (LD) and video compact disc (VCD) player, a compact disc (CD) player, an LP phonograph, the multimedia computer, a television, a power amplifier and a radio tuner. Interactive and mobile '3D airy voices' can be matched with various playing carriers, such as the multimedia computer, an electronic game machine and the like to realize an interactive surround sound conveniently.

Description

The unreal sound of 3D

Technical field

What the unreal sound of 3D set foot in is the computer music making technical field.

Background technology

Getting into digital audio after the epoch; We have experienced several sound equipment experience modes and have changed the stage; Sound technique is actually the process of a sound-reducing, and we realize reduction, several kinds of modes below therefrom having occurred through the sound sample that recording technology is gathered through the equipment of sound equipment:

1, monophony is more original sound reproduction form, is that the back is unified to be noted it by recording equipment mixing from the audio signal of different azimuth, is reset by an audio amplifier again, and this manner of playback sound field position is only in the centre.

2, dual track is made up of two sound channels, on circuit they separately electrical signal delivered be the same, so the sound that two sound channels spread out of also is the same, the sound field position of this play mode is in the middle of only.

3, stereo is exactly the continuity and the development of dual track, and it realizes moving of position, the sound left and right sides on the basis of dual track, but this moving only limits to the plane and move.It can not reduce natural sound and sound position really.

We will welcome the epoch of the unreal sound of 3D today, and this brand-new technology principle will be opened the veil of ears for the mankind, reduce the real world.

The utility model content

The unreal sound of so-called 3D normally compares with normal stereo, is meant that sound seems a kind of mode that is surrounded the hearer.The sound field that this mode produced except the Sounnd source direction sense that is keeping original signal, is also supervened feeling around sense and expansion of sound.

Briefly be exactly; Listening the hearer can clearly distinguish in listening the process of the unreal sound of 3D from up and down sound all around; Be that the unreal sound of 3D can make spatial sound source expand to whole horizontal plane and even vertical plane by line; Therefore can reproduce the space reverberation process in the performance Room realistically, have more moving telepresenc, thereby build a kind of acoustics of placing oneself in the midst of singing-hall, cinema for listening the hearer.

Description of drawings

Fig. 1 is isolation technics figure, and wherein scheme around figure, (7) technological separation graph, (8) technological combined diagram, (9) are infinite around figure, (6) are right more on (1) L channel figure, (2) R channel figure, (3) preposition figure, (4) bass figure, (5) left side.

Fig. 2 is synthetic technology figure, and wherein scheme around figure, (7) technological separation graph, (8) technological combined diagram, (9) are infinite around figure, (6) are right more on (1) L channel figure, (2) R channel figure, (3) preposition figure, (4) bass figure, (5) left side.

Embodiment

The unreal sound of 3D be 2.0 stereophonies realize multichannel logic navigation system around sound field.Like Fig. 1, audio frequency gets into by (7) through (1) and (2), and the computing through (7) can be split as 6 or the audio tracks more than 6 by former 2.0 audio files, is exported by (1), (2), (3), (4), (5), (6), (9).Like Fig. 2, the audio file of these outputs is calculating through (8) once more, will synthesize (1) and (2) two sound channels.Through the calculating that separates like this, synthesizes, people just can enjoy the unreal sound multichannel of 3D logic positioning surrounding sound field effect through common two-channel sterearphone or sound equipment.

Claims

1.3D unreal sound; 2.0 stereophonies realize multichannel logic navigation system around sound field; It is characterized in that; Audio frequency gets into separator through L channel and R channel, be split as L channel, R channel, preposition, bass, a left side around with the right side around 6 audio tracks, the audio frequency of 6 audio frequency synthesizes the new L channel and the audio frequency of R channel through combiner.
