Description
Technical field
The present invention relates to the real-time acquisitions that one kind can carry out audio/video information, and can be with the movement of sound source, can
The method clearly integrated unsharp audio/video information and be able to carry out audio video transmission and preservation.
Background technique
Sampled voice is exactly the process for analog audio-video being changed into digital audio/video, and used capital equipment is mould
Quasi-/(Analog to Digital Converter, i.e. ADC, corresponding be D/A converter to digital quantizer, i.e.,
DAC).The process of sampling is actually that the electric signal of common analog audio-video signal is converted into binary code 0 and 1, these 0
Digital audio/video file is just constituted with 1.The more big then sound quality of the frequency of sampling is more guaranteed.Sound be one kind by object vibration and
The wave of generation makes the narrow gas of surrounding constantly compress and loosen when object vibration, and spreads to surrounding, and here it is sound wave, people
The audio visual rate range that can be heard is 20Hz~20kHz.The format of audio, video data mainly has：WAVE,MOD,
Layer-3, Real Audio, CD Audio etc., the acquisition of audio, video data, common methods have 3 kinds：Directly acquire existing sound view
Frequently, interception sound is captured, with microphone records sound using audio-video processing software.
