Hello everyone, Lin Fei to answer the above questions, Dolby sound shock movie, Dolby sound effect many people do not know, now let's take a look at it!

1. Which SRS sound effect is better than Dolby?

2. Dolby sound effect:

3. Dolby Pro Logic is a surround sound system developed by Dolby Company in the United States. When recording, four-channel stereo is combined into two channels by specific coding means, that is, the four signals of the original left channel (L), right channel (R), middle channel (C) and surround channel (S) are coded into LT and RT compound dual channel signals. During playback, the decoder restores the encoded two-channel composite signals LT and RT into encoded left, right, intermediate and surround signals.

4. SRS sound effect:

5. (voice retrieval system) is the most representative 3D stereoscopic technology developed by SRS Research Institute. It is the general name of a series of patented audio processing technologies based on psychoacoustics. The original SRS 3D audio technology was invented by Arnold Klayman in the early 1980s. It widens the "emperor position" (that is, the best listening area) according to the "head correlation transfer function" (HRTF), creating a wider sound field and locating different instruments very accurately in audio reverberation. Finally, only two speakers are used to create an immersive 3D sound field. This technology is called SRS, or SRS 3D.

6. The above two kinds of sound certification are very common in notebook products, so which is better in the daily use environment? If it is under the stereo of the notebook itself, who wins and who loses?

7. Comparison of audition effect between SRS surround sound system and Dolby decoding surround sound system.

8. Use the same two speakers and switch between SRS and Dolby many times. When using SRS, inspectors often check to see if the rear speakers are working. In fact, the SRS is working on the front main speaker. SRS is clearer than Dube's logic, and surround sound is a continuous three-dimensional sound field that fills the whole space. Dolby is surrounded by five speakers, and the listener feels a flat and two-dimensional sound field.

9. If you put SRS in front of Dolby, the original plane two-dimensional sound field will become a continuous three-dimensional sound field with a sense of space, which will make people feel a real sense of field supervision. SRS makes people feel subjectively that the sound source is distributed in the whole three-dimensional space where the loudspeaker is no longer the sound source. The masking effect between sound sources is much weaker than that of traditional multi-channel systems where sound comes from only a few "points", so the clarity of SRS is higher than that of multi-channel surround sound. In conventional stereo playback, the background noise is reproduced from two loudspeakers (two points), and the noise is concentrated at two points, while the noise of the SRS system is distributed in the whole space. Compared with the concentrated noise of the ordinary stereo system, the background noise of SRS has very little interference to the sound signal, so SRS is better than stereo playback in sound restoration, playback clarity, noise reduction and so on.

10. Through the above comparison, SRS is better, because good external display and 3D surround can give people better audio-visual enjoyment, but only if external sound is needed to achieve the effect. If it's just a small speaker for a laptop or headset, the SRS effect won't work very well. In that case, Dolby's effect may be better for you. After all, headphones have only two playback units.

At the end of this article, I hope it will be helpful to you.
