surround technology, Dolby prologic II. dplii allows the encoding and decoding of stereo surround channels with full bandwidth, with improved Channel Separation and more intelligent logic steering mechanic. it also permits flexible mixing of the LFE channel so that broadcasters can tailor the signal to the end users 'needs. as in dpli, home audiences can switch between stereo and surround sound playback of matrix-encoded content, depending on their p

References summarisation of surveillance videos by key-frame selection icdsc 2011 The idea in this article is roughly the same as that in the previous two articles. This article does not take this step in segments, but directly selects key frames based on a certain selection policy.

bass, which is closely related to the sound mixing of the bass. Generally, this frequency point is full and the tone is thick. On the contrary, the tone is pale and powerless. However, if the tone is too strong, there will often be a low-frequency resonance sound, and there will be a "same sound roar" of "Longlong". Some people will regard it as a "strong sense of attention ", especially around Hz, it is particularly obvious that there is even a drum-like resonance sound. In short, it gives peo

DTS is the abbreviation for "Digital Theatre system", which means "digitized cinema systems". Technically, DTS is completely different from other sound processing systems, including Dolby Digital. Dolby Digital Stores the sound data in the perforation of the film, because the space constraints must be in a large number of compression patterns, which have to sacrifice part of the sound quality. DTS has solved this problem in a simple way, by storing the sound data in another CD-ROM to synchronize

According to statistics, more than 803 of the car friends are custom to enjoy car music or listen to the radio when driving. However, there are departments of car owners will consider the cost of cars, low cost of car audio, the use of cheap and cheap speakers, resulting in the original car equipped with the sound poor, not to enjoy.There are many car owners like to load the car subwoofer, modified the original car audio system, but often these will e

next test is not very optimistic. The center of the speaker, the operating panel, and the distance is 0.03 meters and 0.63 μT. The center of the right side of the speaker is 0.03 meters and 5.68 μT; the radiation is not small, so what is the security distance? After careful tests, it is found that when the distance is 0.4 meters, its radiation is reduced to 0.17 μT. Therefore, the speaker of the subwoofer has severe radiation, and the distance betwee

Band Division In terms of sound quality evaluation and audio system adjustment, the audio range is usually divided into several frequencies. The Rise and Fall of the voice signals in different frequencies are different for the listener, according to different requirements, the audio frequency band can be divided into 3, 4, and 7 segments, audio can be divided into up to seven frequencies, including the subwoofer, mediaintone, mid-tone, high-pitched,
