Problems solved by technology

In the field of surround sound in the traditional system, although the gain of the low frequency channel is 10db higher than that of other channels, the operation method is to directly cut the high frequency of all channels and mix them together, which is realized by a group of reproduction devices.

Embodiment Construction

[0016] Sound processing and reproducing apparatus and method of the present invention

[0017] principle

[0018] All the elements picked up in the natural sound field are reproduced according to different amplification levels, and the elements are not mixed together when they are mixed.

[0019] All the elements picked up in the natural sound field are classified and mixed into several groups, and each group is reproduced according to different amplification levels. When mixing, the sound elements are mixed into several groups according to the creator's requirements.

[0020] The real-time multi-level signal flow generated by the sound signal pickup and judgment device mentioned above is reproduced by multi-level amplification.

[0021] For the traditional single-level signal, the sound signal pickup and judging device mentioned above can be used to pre-amplify the single-level signal to form a multi-level signal stream, which can be reproduced by multi-level amplification. ...

Abstract

The invention provides a sound processing reappearing device, which comprises a processing unit and a reappearing unit which receives a sound signal of the processing unit. Due to the adoption of the sound processing reappearing device, the danger of the audio distortion can be reduced; and the detail and dynamic reappearing capacity of the sound system can be improved; and the reality of the sound listening experience of a sound system simulator in an unnatural sound field can be improved.

Description

technical field [0001] The invention belongs to the field of sound systems, and in particular relates to a sound processing and reproducing device. Background technique [0002] The current Dolby 5.1 is to program the sound into multiple channels, but this channel refers to 5 channels in different directions, and each direction still has only one signal, which cannot be realized in mono, two-channel stereo and surround In the stereo system, the sound in each direction is made into different multiple amplification levels, and it is not possible to form a multi-level dynamic signal in each direction. Moreover, in the process of sound playback, Dolby cuts off the low frequency in the surround channel, then superimposes the low frequency of all channels, and then plays back through a bass channel during playback, increasing 10dB amplification during playback, but it is not full-band Yes, it's not multi-channel either. [0003] Moreover, the existing sound reproduction method a...
