Surround sound audio encoding / decoding formats Know


~ 1l2kbps. Because of its high compression ratio, the ears of the general sense is difficult to hear (and not compressed or low compressed audio signal between: a) significant difference, they have been extensively used online music 』. As computer users can easily download from a number of MP3 music music site. So long to come to the right} if there is suspicion of infringement disputes. Now. In some amplifiers are also integrated into the MP3 decoding. Third, the dual-channel multi-channel audio processing into effect 1, DolbyProLogic: Dolby specifically, the logical (or Dolby Pro Logic) system to matrix technology to record the left, towels central,[link widoczny dla zalogowanych], front right, surround the four-channel __ voice signal reduction in the two-channel five-track, the playback and then decode the signal into four channels, through four power amplifier and four speakers also sound (g [~ 4/2/4 encoder / decoding),[link widoczny dla zalogowanych], the surround channel bandwidth only lOOHz ~ 7000Hz. If the audio equipment in the non-ProLogic decoder can then _ a two-channel audio signals cattle: Digital Integrated Dolby Pro Logic after the equipment can handle any two-channel audio source into a four-channel effect of 2, LogicDolbySurroundProLogic Ⅱ: referred to as PL Ⅱ , Dolby Pro Logic II decoding technology on behalf of Matrix 5.1. Dolby Pro Logic EJj than the aforementioned, in addition to surround-cho separation, increasing the bass channel, all channels are all 20Hz ~ 20kHz bandwidth, full-frequency. Its use can make living in any two-channel source, are similar to the 5.1-channel effect. Objectively speaking, of course. The sound can not be compared with the true multi-channel (the same) = 3, DTSNeo: 6: DTS new 6-channel, is the DTs company for the introduction of the corresponding PL Ⅱ technology, any two-channel sources processed into 6 channel audio (t: LPLII after more central channel). Including cinema and music modes for the corresponding selection, _ port J be music or movies from the most appropriate positioning sense and surround sound. 4, CS A 5.1: United States, SRS, an audio expansion technology, the same two-channel source can be processed into multi-channel audio. SRS has developed now to deal with ant-channel audio into 6.1 channel sound of the latest technology (the other companies in Hong Kong Veyron audio technology developed by a so called, I do not know whether the two sources) 5, DolbyPro-Ix ~ gicIIx: PL Ⅱ Following the latest development after the Dolby matrix decoding technology. Compared with the PL Ⅱ, increased in the surround channels, to the stereo or 5.1 channel signal into 6.1,7.1 channel effect,[link widoczny dla zalogowanych], this should be the most advanced matrix decoding system. Fourth, the audio post-processing technique called audio post-processing techniques, is also the sound source to the audio transmission chain. Added to pure sound, extended bandwidth, improved sound quality and beautify the related audio circuits. Listen to surround sound better or more shocking. One of the most famous is Lucas's THX, THX recognized by Wang where professional theater equipment or civilian equipment, the standards in all aspects of almost demanding. THX include re-balancing (or re-equalization), to the relevant (or related solutions) and the tone matches the three technologies. After treatment the three part of the circuit, you can make high frequency and low frequency sound when playing in a variety of space more balanced, better surround envelopment, more consistent tone of each channel. THX to the listening environment has specific requirements of virtual surround sound (SimulatedSurround or VirtualSurround) is also a very useful in certain circumstances the audio post-processing techniques. Its characteristics and role of people's ears is the use of effects and ear effects, the only two-channel devices (two amplifiers and two speakers), you can still get surround sound effect is similar. The world has a number of companies using different technologies developed by its own unique features,[link widoczny dla zalogowanych], in effect, a virtual surround sound equipment. For example SRS3DPnonicVMAXQSurroundN a 2-2 and so on. Some big companies equipment unique audio processing technology, home-based products enriched and difficult to shake the status of the establishment has played a prominent role, such as Yamaha's DSP sound field sound, Denon's DDSC-Digital surround sound dynamic separation circuit, Sony DCS Digital Cinema Sound, Onkyo's WRAT broadband amplifier technology, Pioneer's MCACC Multi-channel automatic sound field correction technique, crystal company CES7.1 special surround sound and so on. In addition,[link widoczny dla zalogowanych], some manufacturers use in the audiovisual software players and amplifiers, frequency upconversion on the various functions, but also a broad sense of the audio post-processing technology 2004 10 ◆ 35 ◆
